Beijing concerned over US restrictions on Chinese investment

China on Thursday expressed concerns over the "glass door" or "swing door" restrictions on Chinese investment by the United States citing national security concerns.

"Glass door" or "swing door" indicates barriers that are deliberately set by governments to stop foreign direct investment in certain businesses, driven largely by political and economic purposes, but having nothing to do with national security issues.

"We do not oppose normal security reviews by relevant countries over foreign investment," said Gao Feng, a spokesman for the Ministry of Commerce.
