Beijing's Communist Party leaders “further exploited the pandemic to impose their political agenda on many others," Joseph Wu said in a video conference with the Foreign Correspondents'' Club of Japan.

In particular, China's “vaccine diplomacy” is creating divisions among countries in Central and South America, giving Beijing an opportunity to exert its influence in the Western Hemisphere, Wu said.

Beijing is providing access to its domestically produced vaccines, other anti-coronavirus resources and development funding to “those who are willing to accept political partnership with Beijing,” he said.

“China then uses this partnership to lure or pressure those allies of Taiwan and the US to lean toward Beijing. Through these maneuverings, China is trying to gain political influence in the region at the cost of Taiwan and the US.”China says its overseas assistance comes without political conditions, but has aggressively used its economic might in recent years to poach Taiwan''s few remaining allies and erode the influence of the US and other democracies.

Wu said China has already left a “trail of debt, corruption and an erosion of democratic governance” in some countries in Asia, Africa and Europe that agreed to Chinese financing for ports, railways and other infrastructure projects under leader Xi Jinping's signature Belt and Road Initiative that has boosted China's influence abroad.

China has sold hundreds of millions of coronavirus vaccine doses abroad and donated millions more, mainly to developing nations in Africa. The World Health Organisation has given emergency authorisation for two Chinese-developed vaccines, but the companies, particularly Sinopharm, have faced criticism over a lack of transparency in sharing data.

China has shut Taiwan out of an increasing number of international organisations, including the WHO, and has blocked Taiwan's cooperation with the UN organisation's anti-pandemic efforts, including the COVAX initiative that distributes vaccines to middle- and low-income countries, Wu said.

However, he said Taiwan is gaining greater international political support to be included in the WHO as either a member or observer.

“That is helping the Taiwanese people and we really appreciate it," Wu said.

Along with the diplomatic pressure, China has been upping its threat to use military force to bring Taiwan under its control by holding military exercises and sending military aircraft near the island.

Wu said Taiwan's government and citizenry are “absolutely committed to self defense" and the administration is working to boost its military capabilities, including through the purchase of weapons from the United States.

Taiwan split from mainland China during a civil war in 1949 and has never been governed by China's ruling Communists.

Wu also accused Beijing of deliberately raising tensions in the South and East China Seas.

China is employing “all means possible to induce a crisis just below the threshold of a major war," Wu said.

He emphasised the closeness of ties between Japan and Taiwan, a former Japanese colony, despite their lack of formal diplomatic relations.

“Taiwan and Japan share the values of freedom, democracy, human rights protection and the rule of law," Wu said.
