Lai, elected as Taiwan's President last month, in a message posted on X said: “My sincere congratulations to Prime Minister @narendramodi on his election victory. We look forward to enhancing the fast-growing #Taiwan-#India partnership, expanding our collaboration on trade, technology & other sectors to contribute to peace & prosperity in the #IndoPacific.”

China views Taiwan as a rebel province that must be reunified with the mainland, even by force.

Addressing a media briefing, Chinese Foreign Ministry spokesperson Mao Ning said China opposes "all forms of official interactions between the Taiwan authorities and countries having diplomatic relations with China. There is but one China in the world. Taiwan is an inalienable part of the territory of the People's Republic of China".
