The eastern Chinese city of Hangzhou will suspend live poultry trading in its main urban areas, starting on Friday. The move aims to contain the H7N9 bird flu virus from spreading.

The neighboring city of Shanghai will take similar measures during the Spring Festival holidays and beyond. Authorities in Hangzhou are monitoring domestic fowl and birds in poultry farms, the habitats of migratory birds as well as parks.
