New Delhi, Jan 5 (TIWN) China has put a second city under total lockdown after just three asymptomatic Covid cases were discovered from there, the BBC reported.

It follows a similar lockdown in Xi'an, where 13 million have been confined to their homes since December 23.  The strict measures come ahead of the Lunar New Year and the Winter Olympics due to be held in Beijing from February 4-20.  With exactly a month to go until the Games start, Foreign Ministry spokesman Wang Wenbin assured reporters that China has "formulated an efficient and highly effective defence system".
