A store in the Jiulongpo district was caught by a local market regulator selling smoked tea ducks using the meat. The market regulator was tipped off by a consumer late in February, Xinhua said.

Wal-Mart would pay the victims 10 times the price of the ducks as a penalty, the firm told the municipal consumers' association in a statement.

In January, China fined Wal-Mart and France's Carrefour supermarket chain for lying about the price of their goods.
