For the sixth year in a row, the World Health Assembly (WHA) has rejected proposals relating to the Taiwan region, demonstrating the shared international commitment to the one-China principle, an overriding trend that cannot be challenged, a senior Chinese diplomat said on Monday.

Chen Xu, China's Permanent Representative to the UN Office at Geneva, made the remarks during a press conference after the WHA, the highest decision-making body of the World Health Organization (WHO), refused to include a proposal on Taiwan's participation in its agenda.
