China's "reunification" with Taiwan is inevitable, leader Xi Jinping said in his New Year's address on Sunday, striking a stronger tone than he did last year with less than two weeks to go before the Chinese-claimed island elects a new leader.

The Jan. 13 presidential and parliamentary elections are happening at a time of fraught relations between Beijing and Taipei. China has been ramping up military pressure to assert its sovereignty claims over democratically governed Taiwan.

China considers Taiwan to be its "sacred territory" and has never renounced the use of force to bring it under Chinese control, though Xi made no mention of military threats in his speech carried on state television.
