China views Tsai, who will be sworn into office for her second and final term on Wednesday, as a separatist bent on formal independence for Taiwan. She says Taiwan is already an independent state called the Republic of China, its official name.
Tsai will say at her inauguration that Taiwan will seek to "actively participate" in international bodies and deepen its cooperation with like-minded countries, generally a reference to the United States and its allies, according to an outline of her speech provided by Presidential Office spokesman Alex Huang.
Taiwan sees the need for participation in WHO as all the more urgent because of the coronavirus pandemic, which was first reported in China.
Despite an intense lobbying effort and strong support from the United States, Japan, Britain, Germany, Australia, New Zealand and others, it was unable to take part in this week's meeting of the World Health Assembly.
On relations with China, Tsai will reiterate her commitment to peace, dialogue and equality, but that Taiwan will not accept China's "one country, two systems" model that "belittles" Taiwan.
China uses this system, which is supposed to guarantee a high degree of autonomy, to run the former British colony of Hong Kong, which returned to Chinese rule in 1997. It has offered it to Taiwan too, though all major Taiwanese parties have rejected it.
Tsai will also pledge to speed up the development of "asymmetric warfare" capabilities, and boost renewable technologies in a move to position Taiwan as a hub of clean energy in the Asia Pacific.
