China will not change its position that Taiwan belongs to it, Beijing said on Sunday, after President Tsai Ing-wen won re-election and said she would not submit to China's threats, as state media warned she was courting disaster.

The election campaign was dominated by China's ramped-up efforts to get the democratic island to accept Beijing's rule under a "one country, two systems" model, as well as by anti-government protests in Chinese-ruled Hong Kong.

Premier Li says China opposes Taiwan independence

"No matter what changes there are to the internal situation in Taiwan, the basic fact that there is only one China in the world and Taiwan is part of China will not change," China's Foreign Ministry said in a statement, responding to the result.

While China says Taiwan is its territory, Taiwan maintains it is an independent country called the Republic of China, its formal name.

Tsai, who has firmly rejected China's "one country, two systems" model, won another four-year term by a landslide, and her Democratic Progressive Party (DPP) secured a majority in parliament.

Speaking on Saturday after the scale of her victory become clear, Tsai called for talks to resume with China, but said she hoped Beijing understood Taiwan and its people would not submit to intimidation.

China will not change its stance sticking to the "one China" principle and opposing independence for Taiwan, the Chinese foreign ministry said.

"The universal consensus of the international community adhering to the 'one China' principle will not change either."

China hoped the world would understand and support the "just cause" of Chinese people to oppose secessionist activities and "realise national reunification", it added.

Taiwan's Mainland Affairs Council said China should respect the election result and stop putting pressure on the island.

"Our government will firmly defend the sovereignty of the Republic of China and Taiwan's democracy and freedom," it said.
