122 countries adopt global treaty banning nuclear weapons

Beijing, Feb 24: The lockdown of Guo Jing's neighbourhood in Wuhan -- the city at the heart of China's new coronavirus epidemic -- came suddenly and without warning.

Unable to go out, the 29-year-old is now sealed inside her compound where she has to depend on online group-buying services to get food.

"Living for at least another month isn't an issue," Guo told news agency, explaining that she had her own stash of pickled vegetables and salted eggs.

But what scares her most is the lack of control -- first, the entire city was sealed off, and then residents were limited to exiting their compound once every three days.

Now even that has been taken away.

Guo is among some 11 million residents in Wuhan, a city in central Hubei province that has been under effective quarantine since January 23 as Chinese authorities race to contain the epidemic.

Since then, its people have faced a number of tightening controls over daily life as the death toll from the virus swelled to over 2,500 in China alone.

But the new rules this month barring residents from leaving their neighbourhoods are the most restrictive yet -- and for some, threaten their livelihoods.

"I still don't know where to buy things once we've finished eating what we have at home," said Pan Hongsheng, who lives with his wife and two children.

Some neighbourhoods have organised group-buying services, where supermarkets deliver orders in bulk.

But in Pan's community, "no one cares".

"The three-year-old doesn't even have any milk powder left," Pan told news agency, adding that he has been unable to send medicine to his in-laws -- both in their eighties -- as they live in a different area.

"I feel like a refugee."

The "closed management of neighbourhoods is bound to bring some inconvenience to the lives of the people", Qian Yuankun, vice secretary of Hubei's Communist Party committee, said at a press briefing last week.

Authorities on Monday allowed healthy non-residents of the city to leave if they never had contact with patients, but restrictions remained on those who live in Wuhan.

Demand for group-buying food delivery services has rocketed with the new restrictions, with supermarkets and neighbourhood committees scrambling to fill orders.

Most group-buying services operate through Chinese messaging app WeChat, which has ad-hoc chat groups for meat, vegetables, milk -- even "hot dry noodles", a famous Wuhan dish.

More sophisticated shops and compounds have their own mini-app inside WeChat, where residents can choose packages priced by weight before orders are sent in bulk to grocery stores.

In Guo's neighbourhood, for instance, a 6.5-kilogramme (14.3-pound) set of five vegetables, including potatoes and baby cabbage, costs 50 yuan ($7.11).

"You have no way to choose what you like to eat," Guo said. "You cannot have personal preferences anymore."

The group-buying model is also more difficult for smaller communities to adopt, as supermarkets have minimum order requirements for delivery.

"To be honest, there's nothing we can do," said Yang Nan, manager of Lao Cun Zhang supermarket, which requires a minimum of 30 orders.

"We only have four cars," she said, explaining that the store did not have the staff to handle smaller orders.

Another supermarket told AFP it capped its daily delivery load to 1,000 orders per day.

"Hiring staff is difficult," said Wang Xiuwen, who works at the store's logistics division, adding that they are wary about hiring too many outsiders for fear of infection.

Closing off communities has split the city into silos, with different neighbourhoods rolling out controls of varying intensity.

In some compounds, residents have easier access to food -- albeit a smaller selection than normal -- and one woman said her family pays delivery drivers to run grocery errands.

Her compound has not been sealed off either, the 24-year-old told AFP under condition of anonymity, though they are limited to one person leaving at a time.

Some districts have implemented their own rules, such as prohibiting supermarkets from selling to individuals, forcing neighbourhoods to buy in bulk or not at all.

"In the neighbourhood where I live, the reality is really terrible," said David Dai, who is based on the outskirts of Wuhan.

Though his apartment complex has organised group-buying, Dai said residents were unhappy with price and quality.

"A lot of tomatoes, a lot of onions -- they were already rotten," he told , estimating over a third of the food had to be thrown away.

His family must "totally depend" on themselves, added the 49-year-old, who has resorted to saving and drying turnip skins to add nutrients to future meals.

The uncertainty of not knowing when the controls will be lifted is also frustrating, said Ma Chen, a man in his 30s who lives alone.

"I have no way of knowing how much (food) I should buy."

Melbourne, Mar 18: Australian Prime Minister Scott Morrison on Wednesday warned its citizens not to travel abroad and banned "non-essential" gatherings of 100 people or more as the government declared the deadly coronavirus, that has infected over 450 people in the country, a "human biosecurity emergency".

Prime Minister Morrison on Wednesday said Australians should abandon all overseas travel because of the coronavirus epidemic. There have been 40 new cases since Tuesday.

Of the 454 confirmed cases in Australia, 43 have recovered and 5 have died from the COVID-19, according to the official figures.

Morrison declared a national "human biosecurity emergency" and ordered a halt to "non-essential" indoor gatherings of more than 100 people, on top of an existing ban on outdoor events of more than 500.

He said, "We haven't seen this sort of thing in Australia since the end of the First World War. This is a once-in-a-100-year-type event," Morrison said.

"Life is changing in Australia, as it is changing all around the world. Life is going to continue to change. The travel advice to every Australian is do not travel abroad. Do not go overseas."

However, schools across the country were still to remain open.

Morrison said Australia should prepare for "at least six months" of disruption as health authorities attempt to get on top of the coronavirus.

"For those of you thinking about going overseas for the school holidays, don’t. Don't go overseas," he said.

Morrison said there would be no short-term, quick fix to deal with the COVID-19 crisis in Australia, and warned that "tens of thousands of jobs" could be lost.

Responding to the panic buying, the prime minister urged the public to "Stop hoarding."

"I can't be more blunt about it. Stop it. It is not sensible, it is not helpful and it has been one of the most disappointing things I have seen in Australian behaviour in response to this crisis," he said.

On Wednesday, the New South Wales recorded a massive jump in new 59 cases as travellers returned from overseas. The cases jumped from 210 to 269 in the past 24 hours, according to the media reports here.

Queensland's total number of confirmed cases stood at 94.

State Premier Annastacia Palaszczuk said it is now "a different world" from just last week.

For Victoria, the Premier Daniel Andrew said the government could also ban gatherings of fewer than 100 people, noting he could not rule out further changes.

Chief Health Officer Brett Sutton said the spike in cases has been due to people who have travelled overseas.

Sutton said that the transmission in Victoria was not because of community transition like Italy.

Sutton has continued to urge people to wash their hands, socially distance and stay home if they are unwell.

"These are critical measures to be applied regardless of the 100 and 500 threshold,” he said.

In Western Australia, Health Minister Roger Cook said four new coronavirus cases have been confirmed overnight, taking the State's total to 35.

McGowan also condemned panic buyers in supermarkets as "jerks, drongos and bloody idiots."

He said there was "plenty of food to go round" and no need for people to buy in excessive quantities.

The outbreak, which first emerged in China's Wuhan city last year, has marched across the globe, infecting 198,006 people and killing 7,948, according to a tracker maintained by the Johns Hopkins University.

Washington, May 30: President Donald Trump said Friday he would strip several of Hong Kong's special privileges with the United States and bar some Chinese students from US universities in anger over Beijing's bid to exert control in the financial hub.

In a day of concerted action, the United States and Britain also raised alarm at the UN Security Council over a controversial new security law for Hong Kong, angering Beijing which said the issue had no place at the world body.

In a White House appearance that Trump had teased for a day, the US president attacked China over its treatment of the former British colony, saying it was "diminishing the city's longstanding and proud status."

"This is a tragedy for the people of Hong Kong, the people of China and indeed the people of the world," Trump said.

Trump also said he was terminating the US relationship with the World Health Organization, which he has accused of pro-China bias in its management of the coronavirus crisis.

But Trump was light on specifics and notably avoided personal criticism of President Xi Jinping, with whom he has boasted of having a friendship even as the two powers feud over a rising range of issues.

"I am directing my administration to begin the process of eliminating policy that gives Hong Kong different and special treatment," Trump said.

"This will affect the full range of agreements, from our extradition treaty to our export controls on dual-use technologies and more, with few exceptions," he said.

Secretary of State Mike Pompeo on Wednesday informed Congress that the Trump administration would no longer consider Hong Kong to be separate under US law, but it was up to Trump to spell out the consequences.

China this week pressed ahead on a law that would ban subversion and other perceived offenses against its rule in Hong Kong, which was rocked by months of massive pro-democracy protests last year.

US restricts students

In one move that could have long-reaching consequences, Trump issued an order to ban graduate students from US universities who are connected to China's military.

"For years, the government of China has conducted elicit espionage to steal our industrial secrets, of which there are many," Trump said.

Hawkish Republicans have been clamoring to kick out Chinese students enrolled in sensitive fields. The FBI in February said it was investigating 1,000 cases of Chinese economic espionage and technological theft.

But any move to deter students is unwelcome for US universities, which rely increasingly on tuition from foreigners and have already been hit hard by the COVID-19 shutdown.

China has been the top source of foreign students to the United States for the past decade with nearly 370,000 Chinese at US universities, although Trump's order will not directly affect undergraduates.

Critics say Trump has been eager to fan outrage about China to deflect attention from his own handling of the coronavirus pandemic that has killed more than 100,000 people in the United States, the highest number of deaths of any country.

Chuck Schumer, the top Democrat in the Senate, called Trump's announcement "just pathetic."

Eliot Engel, a Democrat who heads the House Foreign Affairs Committee, noted that Trump treaded lightly on Hong Kong during last year's protests as he sought a trade deal with Xi.

"Now, the president wants to shift the blame for his failures onto China, so he's doing the right thing for the wrong reason," Engel said.

Trump's order could also trigger retaliation. China in March expelled US journalists after the Trump administration tightened visa rules for staff at Chinese state media.

Clash at UN

The United States and Britain earlier in the day urged China to reconsider the Hong Kong law during talks at the UN Security Council, where China wields a veto -- making any formal session, let alone action against Beijing, impossible.

The Western allies raised Hong Kong in an informal, closed-door videoconference where China cannot block the agenda.

They said China was violating an international commitment as the 1984 handover agreement with Britain, in which Beijing promised to maintain the financial hub's separate system until at least 2047, was registered with the United Nations.

"The United States is resolute, and calls upon all UN members states to join us in demanding that the PRC immediately reverse course and honor its international legal commitments to this institution and to the Hong Kong people," said US Ambassador Kelly Craft, referring to the People's Republic of China.  

China demanded that the United States and Britain "immediately stop interfering in Hong Kong affairs," saying the law did not fall under the Security Council's mandate.

"Any attempt to use Hong Kong to interfere in China's internal matters is doomed to fail," warned a statement from China's UN mission.

"There was no consensus, no formal discussion in the Security Council, and the US and the UK's move came to nothing," it said.
