China's booming economy could be impacted by global rejection of products with made in China labels after a host of recalls of unsafe pet food, toothpaste, toys, tires and seafood in recent months.

To bolster public acceptance of Chinese products, the government Wednesday declared a four-month "special battle" against poor product quality and supervision.

The war extends to eight kinds of products - drugs, pork, farm products, processed food, food in the catering sector, import and export products, and other products related to public health such as toys and electric wires, the official state news agency Xinhua reports.

"This is a special battle to protect the safety and interests of the general public, as well as a war to safeguard the made-in-China label and the country's image," Vice-Premier Wu Yi told a national teleconference in Beijing.
