China strongly deplores and firmly opposes the G7 allegations of the South China Sea and China's economic policies, and has lodged serious protests to the Canadian side, the Chinese Embassy in Canada said on Saturday.

The Statement of the G7 Foreign Ministers' Meeting and G7 Foreign Ministers Declaration on Maritime Security and Prosperity "grossly interfered in China's internal affairs, and maliciously slandered and smeared China," said a spokesperson of the embassy.
