An online green agri-product promotion platform was launched Wednesday in eastern China's Shanghai.

Residents will be able to search for locally produced green agri-products via a mobile app, together with the products' sales links and green food certificates issued by China's Ministry of Agriculture and Rural Affairs.

Shanghai is working on the production technologies and equipment of green agri-products, with an aim to reach a 30 percent certification rate of green agri-products.

So far, a total of 955 products have been certified, with an annual output of 951,900 tonnes.

The platform will help raise the residents' awareness of green agri-products and improve the production and certification monitoring of green agri-products, said Fang Fang, deputy director with Shanghai Municipal Agricultural Commission.
