BEIJING -- China on Friday said the United States should adhere to one-China policy and properly handle issues regrading Taiwan.

"We hope the US will abide by one-China policy and principles of the three China-U.S joint communiques," Foreign Ministry spokesperson Geng Shuang said when answering a question on the American Institute in Taiwan (AIT).

According to reports, a former chief of the AIT Thursday said that the US side will send marine corps to protect the new AIT site.

"China has always objected US-Taiwan connections through official and military channels," Geng said, adding that China will keep an eye on the situation.
