The pro-Taiwan leader of the Pacific islands nation of Tuvalu, Kausea Natano, lost his seat in an election closely watched by Taiwan, China and the U.S., partial results showed on Saturday.

Tuvalu, with a population of about 11,200 spread across nine islands, is one of three remaining Pacific allies of Taiwan, after Nauru cut ties this month and switched to Beijing, which had promised more development help.

Natano had pledged to continue support for Taiwan, a diplomatic ally since 1979. Another leadership contender, Seve Paeniu, has said diplomatic ties should be reviewed, with the new government deciding whether Taiwan or China can best respond to Tuvalu's needs.
