Beijing is "very disappointed" with plans in Europe to restrict investment from China, Chinese diplomat Qu Xun told a conference ​in Madrid on Wednesday, warning that such measures would push China to "close its door" to Europe, Reuters reported. 

In unusually candid public remarks for a Chinese official, Qu, the commercial representative at China's embassy in Spain, said the "controls, limitations, and sanctions ​by Europe towards China in the past three months make us ​very disappointed."

"Such measures push us into corners, to react and ⁠close the door. It changes the Chinese mentality," he said, speaking ​on a panel at an event at Madrid's IESE Business School, adding that ​China had always viewed Europe as a region with an "open mind".
