A Chinese mainland spokesman on Monday urged Taiwan's Democratic Progressive Party to stop their grandstanding over participating as an observer in this year's World Health Assembly.

"Any attempts that challenge the one-China principle will not succeed and will not be accepted by the people," said Ma Xiaoguang, spokesman for the Taiwan Affairs Office of the State Council.

Ma made the remarks while responding to a question regarding the decision of the 76th WHA not to include the proposal submitted by a small number of countries regarding inviting Taiwan to participate in the assembly as an observer.

Ma said Taiwan is a part of China, and the decision of the 76th WHA reaffirmed the one-China principle as a universal consensus of the international community.

He criticized the DPP for not recognizing the 1992 Consensus which embodies the one-China principle by attempting to raise the proposal.

"Any challenge to the one-China principle is bound to fail," he added.
