China’s foreign ministry did not immediately respond to a request for comment
Forum 2000, which will hold its summit in Prague from Oct 13 to Oct 15, also did not immediately respond to a request for comment.
China staged two rounds of war games around Taiwan during Tsai’s second term in office – in 2022 after then-US House Speaker Nancy Pelosi visited Taipei, and in 2023 after Tsai returned from a visit to the United States where she met Pelosi’s successor Kevin McCarthy.
Tsai, who has a doctorate from the London School of Economics, is also due to visit two other European countries but details are not finalised, the sources said.
In January 2023, Tsai held a call with Czech President-elect Petr Pavel, a diplomatic coup for Taiwan that angered China.
Tsai’s vice president Lai Ching-te won election in January of this year, and took over from Tsai in May.
Tsai remains a senior and influential member of the ruling Democratic Progressive Party (DPP) as a senior statesperson.
China detests Lai and his party as “separatists” who refuse to recognise Beijing’s position that democratically-governed Taiwan is a part of China.
Lai, Tsai and the DPP reject Beijing’s sovereignty claims, saying only Taiwan’s people can decide their future.
Tsai’s predecessor Ma Ying-jeou, from what is currently Taiwan’s largest opposition party the Kuomintang (KMT), frequently makes overseas trips though without drawing Beijing’s ire.
Ma has met Chinese President Xi Jinping twice. The first was an historic summit in Singapore in late 2015 just before Ma left office, and the second was earlier this year in Beijing.
The KMT advocates closer ties with China but strongly denies being pro-Beijing.
