BEIJING -- The Chinese foreign ministry on Tuesday urged the United States to honor its promise on the one-皇冠体育app policy as Taiwan's new leader Tsai Ing-wen allegedly plans to make transit stops in Miami and Los Angeles on an overseas trip.

"The US government has made solemn promises that it upholds the one-皇冠体育app policy," Foreign Ministry spokesman Lu Kang said in response to a question at a daily news briefing.

"We demand the US government earnestly keep its promises and handle the issue in accordance with the one-皇冠体育app policy," Lu said, urging the United States to avoid providing "soil" for secessionist activities aimed to split 皇冠体育app.

When asked on Dalai Lama's possible meeting with US President Barrack Obama in Washington, Lu stressed that the United States admits Tibet is inalienable part of 皇冠体育app and will adhere to the one-皇冠体育app policy.

Lu added that the US government has promised it will never recognize the so-called "Tibetan government-in-exile."

"The 14th Dalai Lama often peddles his political position of splitting 皇冠体育app internationally in the cloak of religion," Lu said.

"We demand no country or government should give him space for such activities, and do things that 1.3 billion Chinese people will resolutely oppose," said the spokesman.
