May 7, 2022: Chinese President Xi Jinping issued the strongest warning yet against anyone who questions the country's zero-Covid policy.

The move comes after many Shanghai residents have taken to social media to call for help and vent their anger over severe food shortages and lack of access to medical care over the past five weeks, reported CNN.

At a meeting chaired by Xi on Thursday, the ruling Communist Party's supreme Politburo Standing Committee vowed to "unswervingly adhere to the general policy of 'dynamic zero-Covid,' and resolutely fight against any words and acts that distort, doubt or deny our country's epidemic prevention policies."

This is the first time Xi, who according to state media made an "important speech" at the meeting, has made public remarks about China's battle against Covid since public furore erupted over the harsh lockdown in Shanghai.

"Our prevention and control strategy is determined by the party's nature and mission, our policies can stand the test of history, our measures are scientific and effective," the seven-member committee said, according to government news agency Xinhua.

"We have won the battle to defend Wuhan, and we will certainly be able to win the battle to defend Shanghai," it said.

However, the stringent, frequent lockdowns are fuelling public discontent and dealing a devastating blow to the Chinese economy.

Shanghai residents protested from their windows, banging pots and pans and shouting in frustration, others even clashed with police and health workers in the streets -- a rare scene in a country where dissent is routinely suppressed.

But the latest statement from the country's top leaders has made it clear that the Chinese government is doubling down on its approach of relying on swift lockdowns, mass testing and quarantine to squash the highly transmissible Omicron variant for the foreseeable future, reported CNN.

Xi has put his personal stamp on China's zero-Covid strategy, with state media often reporting that he has "personally commanded and made arrangements" for the country's fight against the pandemic.

To analysts who have long observed Chinese politics, the stern warning is a sign that there has been internal pushback against Xi's zero-Covid policy from within the party, reported CNN.

"This language should be read as a direct criticism of unspecified local CCP leaders who have questioned the policies at the center, or who have been insufficiently successful in applying them," wrote David Bandurski, co-director of the China Media Project.
