BEIJING,   (Xinhua) - The US side should stop interfering in China's internal affairs or undermining the development and stability of the country's Tibet region under the pretext of Tibet-related matters, a foreign ministry spokesperson said Tuesday.

The United States shall not in any way support anti-China separatist activities by "Tibetan independence" forces, foreign ministry spokesman Zhao Lijian told a press briefing while commenting on a meeting between Lobsang Sangay, head of the so-called "Tibetan government-in -exile," with US Assistant Secretary of State Robert Destro.

Destro's meeting with Lobsang Sangay seriously breached the US commitment and policy stance of not supporting so-called "Tibetan independence" and not recognizing the so-called "Tibetan government-in-exile", sending a deeply erroneous signal to the "Tibetan independence" forces, Zhao said.

"China will take all necessary measures to safeguard its interests," he said, adding that Tibet's affairs are China's internal affairs that allow no foreign interference.

The US appointment of Destro as the so-called "special coordinator for Tibetan issues" is a political manipulation to interfere in China's domestic affairs and undermine Tibet's development and stability, Zhao said. "China firmly opposes it and has never recognized it. We have lodged solemn representations with the US side."

The so-called "Tibetan government-in-exile" is a separatist political organization with the agenda of pursuing "Tibetan independence," he said, adding that Lobsang Sangay is utterly an anti-China separatist.

"China firmly opposes Lobsang Sangay conducting anti-China separatist activities in whatever capacity, name or country, and we firmly oppose engagement of whatever form between him and officials of any country," Zhao said.  ■
