China will remain firmly committed to high-level opening-up and support building an open world economy, a Chinese foreign ministry spokesperson said on Thursday.

In response to a query regarding the U.S. export controls on semiconductors to China and the EU anti-subsidy investigation into electric vehicles from China at a daily news briefing, spokesperson Mao Ning said that openness brings progress while isolation only holds one back.

Noting that China has recently announced it will remove all restrictions on foreign investment access in the manufacturing sector, Mao said this speaks volume to China's determination to take the initiative in opening up further to the world.

She added that the ongoing 134th China Import and Export Fair has attracted numerous businesses and participants.

Next month, China will host the China International Import Expo (CIIE) in Shanghai and the Global Digital Trade Expo in Hangzhou, Zhejiang Province.

For this year's CIIE, the scale of Business Exhibition and the numbers of participating Fortune 500 companies and leading companies in various sectors will hit record high, according to Mao.

"The history of global economic development tells us that one will only get trapped by opting for protectionism, and will not succeed or go far by pursuing decoupling or severing of industrial and supply chains," said the spokesperson.
