BEIJING, May 21 (Xinhua) -- The World Health Assembly (WHA) decision not to include a proposal to make Taiwan an observer in its provisional agenda proves that the one-China principle represents the "popular will," a Foreign Ministry spokesperson said Tuesday.

The 72nd session of the WHA, the decision-making body of World Health Organization, has once again refused to include the so-called proposal of "inviting Taiwan to attend the WHA as an observer" in the conference's provisional agenda, spokesperson Lu Kang told a press briefing.

The decision accords with relevant resolutions of the UN General Assembly and the WHA, Lu said. "It fully demonstrates that the one-China principle represents the popular will of the international community, it conforms to the general trend and shall not be challenged."

"We'd like to reiterate that Taiwan's participation in the activities of international organizations must and can only be dealt with according to the one-China principle," Lu added.
