Taiwanese voters rejected a bid to oust about one-fifth of their lawmakers, all from the opposition Nationalist Party, in a recall election Saturday, dampening hopes for the ruling party to flip the balance of power in the self-ruled island's legislature.

The vote has coincided with efforts by Beijing to raise its military and diplomatic pressure on Taiwan. China has for decades claimed sovereignty over Taiwan and has never renounced the possible use of force to annex the self-governing island and unify it with the Chinese mainland.
