China will continue its efforts to open up the economy and reduce market access restrictions on foreign investment, the Ministry of Commerce said.

“The country will continue to optimize the environment for foreign investment, improve the transparency of market supervision and better protect foreign companies operating in China,” said Gao Feng, the ministry’s spokesman.

In addition, China will strive to address the reasonable concerns of foreign investors and create a more favorable investment environment for them, Gao said at a news conference on Thursday.

Gao made the remarks as an AmCham China report showed that China remains a high priority market for the majority of U.S. companies surveyed, despite trade tensions.

Fifty percent of the companies surveyed are optimistic that steps will be taken to open markets further for foreign companies in China-the highest level since the survey was initiated in late 2016, according to the 2019 China Business Climate Survey Report.
