TAIPEI (Reuters) - Taiwan went to the polls on Saturday toelect a president who could usher in a new era in relationswith political rival China in one of the hottest potentialflashpoints in Asia.
Taiwan's more than 17 million voters will choose asuccessor to President Chen Shui-bian, an anti-China firebrandwho steps down in May and who has repeatedly angered Beijingwith his pro-independence rhetoric.
China has claimed self-ruled Taiwan as its territory sincethe end of the Chinese civil war in 1949 and has pledged tobring it under its rule, by force if necessary.
Frank Hsieh's ruling Democratic Progressive Party favoursformal independence while Nationalist Party candidate MaYing-jeou wants reunification once China embraces democracy.
"Whether you vote for Hsieh or for Ma, be sure to vote forTaiwan," Chen told reporters after voting with his wife."...Don't let Taiwan become the next Hong Kong. Don't letTaiwan become the next Tibet."
The former British colony of Hong Kong returned to Chineserule in 1997. Chinese troops marched into Tibet, the scene ofanti-Chinese rioting last week, in 1950.
The polls close at 8 a.m. British time and a result isexpected a few hours later.
The election has drawn keen international attention, withthe United States, Russia and Britain criticising a referendumon U.N. membership, to be held alongside the vote, which theybelieve could upset the delicate balance with China.
Whatever the referendum result, U.N. membership is out ofthe question with just 23 countries recognising Taiwan, andwith China a veto-wielding permanent member of the U.N.Security Council.
The United States switched diplomatic recognition fromTaiwan to China in 1979, recognising "one China", but remainsthe island's biggest ally.
Two U.S. aircraft carriers are in the region for trainingexercises. China fired missiles into the Taiwan Strait in 1996,trying to intimidate voters during an election.
"China hopes the United States and Japan will carry outtheir promises of not supporting 'Taiwan independence' orTaiwan authority's proposed 'referendum on U.N. membership',"Chinese Foreign Minister Yang Jiechi said in an interview withRussia's Interfax news agency.
In Taiwan, a faltering economy is a priority with voters.
"Domestic issues, such as the economy and corruption, arebigger than China or foreign policy," said Ralph Cossa,president of the U.S.-based think tank Pacific Forum CSIS.
The two candidates have toughened their stances on Chinafollowing Beijing's crackdown in Tibet, but to help theeconomy, both advocate more direct flights, tourism andinvestment opportunities between Taiwan and China.
Ma advocates a common market with China.
"I'd like to see us become the Switzerland of the east, notthe Cuba of the east," he told a campaign rally late on Friday.
Hsieh says that could cause Taiwan to be flooded by Chineselabourers and shoddy products, and the island may end upsuffering the same fate as Tibet.
On the campaign trail, both camps have marshalled tens ofthousands of people at noisy rallies up and down the island.
Both have trotted out groups of attractive young women toget attention and have run television commercials that play onvoter fears such as China or a government fractured bybickering.
Yet voters are smarter, more practical and more fatiguedthan ever by politicking, analysts say.
"For me, the key topic is economic improvement," saidTaiwan voter Mei Yi-ying, 60. "Most of us at our age want towork."
