BEIJING — China announced two new cases of coronavirus, both from abroad, on Thursday as it moves to close the annual session of its ceremonial legislature that had been delayed for more than two months by the outbreak.

No new deaths were reported and just 73 people remained in treatment, while another 518 remain under isolation and observation for either suspected of having the virus or testing positive without showing any symptoms. China has reported a total of 4,634 deaths from COVID-19 among 82,995 cases.

The National People’s Congress is to conclude its meetings later Thursday with a news conference given by Premier Li Keqiang. Delegates to the congress have worn masked during full meetings at the Great Hall of the People although leaders such as Li and President Xi Jinping have generally gone without. On Wednesday, the congress’s advisory body held its closing session at which its chairperson,

Wang Yang, said it came at an “important time when major strategic achievements have been made by China in fighting COVID-19 and when China is endeavoring to secure a decisive victory in completing building a moderately prosperous society in all respects.”
