In response to a reporter’s question that letters issued by US government departments to all US state governors, officials and business leaders alleges Chinese Embassy in the US has contacted local government officials and private enterprises in US to dissuade them from having exchanges with the Taiwan region and distorted US policies, Chinese Foreign Ministry spokesperson Guo Jiakun said on Thursday that China has always firmly opposed any form of official exchanges between the US and China’s Taiwan region. It is an explicit commitment the US made in the Joint Communiqué on the Establishment of Diplomatic Relations between China and the US that both the US federal and local governments should maintain only unofficial ties with Taiwan.
