China on Thursday demanded Libya cease all its official ties with Taiwan, in a bid to maintain the overall China-Libya relations.

"We are strongly dissatisfied with Libya and have lodged solemn representations to Libya," Chinese Foreign Ministry spokesman Liu Jianchao told the regular briefing.

Despite China's persuasion and strong opposition, Libya allowed Taiwan leader Chen Shui-bian to make a transit stop in Tripoli, capital of Libya, Wednesday. The Libyan government also held talks with Chen on mutually establishing representative offices.

"This is a serious violation of Libya's long-term commitment to the one-China policy and will exert a negative impact on China-Libya relations," Liu said.

"We demand that Libya live up to its commitment and immediately cease all official exchanges with Taiwan in whatever forms so as to maintain the overall China-Libya relations," the spokesman said.
