The Chinese Foreign Ministry on Monday refused to accept the Group of Seven's (G7) unilateral accusation of implementing "non-market" policies and practices.

Ministry spokesperson Mao Ning made the remarks at a regular press briefing in response to a query on the G7 hyping up the so-called Chinese overcapacity.

Mao said the success of China's economy over the past 40 years is the result of reform and opening up, and the result of the effective combination of the role of the market mechanism and the government.

"In fact, the discriminatory practices adopted by a few Western countries against specific countries and companies are truly non-market practices," she said.

The G7 is hyping up the so-called Chinese overcapacity in an attempt to impose restrictions on China's new energy products, said Mao, adding that such an act completely deviates from facts and economic regulations and is protectionism in nature, serving no interests of any party.
