China has announced plans to buy 200 aircraft from Boeing, "in accordance with market demand", following the consensus reached by the leaders of China and the US.

An official from the Department of American and Oceanian Affairs at China's Ministry of Commerce said on Wednesday that aviation is a key sector for mutually beneficial and win-win cooperation between the two countries.

Chinese airlines will introduce 200 Boeing aircraft "in accordance with market demand and on commercial principles", the official said in response to a request for more details on United States President Donald Trump's claim that China has agreed to purchase 200 Boeing aircraft.

The United States will in turn ensure sufficient supply of engines and spare parts for Chinese operators, according to a statement on the ministry's website.

Analysts say aircraft orders have long reflected the broader political climate between Beijing and Washington.
