Taiwan says it is in the United States' security and economic interests to support the self-governing island as it seeks to acquire new weaponry in the face of China's military buildup.
Visiting Taiwan government spokesman Philip Yang said Friday the island's engagement with mainland China in the past three years has eased tensions across the Taiwan Strait and in east Asia.
But he told a news conference that U.S. support for Taiwan's self-defense remains vital.
Yang dismissed as guesswork reports that Vice President Joe Biden would inform Beijing during a visit next month that the U.S. would not supply the next-generation fighter jets that Taiwan seeks.
China regards Taiwan as part of its territory and strongly opposes such arms sales.
