A US congressional delegation has arrived for an unannounced visit to Taiwan, 12 days after a tour of the island by House Speaker Nancy Pelosi.
Five members of Congress will visit until Monday, said Washington's de-facto embassy in the capital Taipei.
China launched its largest-ever military exercises around Taiwan after Ms Pelosi's visit earlier in August.
Beijing sees the self-governing island as its own, renegade territory that must be united with the mainland.
It believes that mission could be necessary with force, if other attempts at unification are unsuccessful.
Ms Pelosi became the most senior American politician to visit the island in 25 years during her appearance earlier this month.
