BEIJING — Many big farm produce wholesale markets and supermarket chains returned to normal operation on Feb 10, an official with the Ministry of Commerce said.

Fifty big wholesale markets of agricultural products supervised by the ministry have all opened for business, Zhu Xiaoliang, director of the ministry's market system development department, told an online news conference.

Over 92 percent of more than 7,000 supermarket outlets in 34 large and medium-sized cities across the country have also resumed operation, he said.

The ministry will continue to closely monitor the operation of wholesale markets and commercial outlets to keep track of inventory and price changes and ensure sufficient supplies of daily necessities, Zhu said.

The country has released frozen pork reserves and increased imports to ensure supplies of food and medical gear amid the novel coronavirus outbreak.
