On Thursday, Taiwanese Foreign Minister Joseph Wu told reporters that he appreciated Japan’s consideration of supplying COVID-19 vaccinations and that Taiwan’s exclusion from the World Health Organization was unjust to the Taiwanese people.

When asked about Taiwan’s relations with Japan, Wu cited Japanese Foreign Minister Toshimitsu Motegi as saying that the Japanese government is considering giving vaccines to Taiwan.

Taiwan has only received vaccines from Moderna Inc and AstraZeneca Plc. It has accused China of obstructing a sale for doses of a vaccine developed by German drugmaker BioNTech SE. China claims Taiwan as its own territory.

Beijing denies the charges.

Germany’s top diplomat in Taiwan said Wednesday that his government has been helping in talks between Taiwan and BioNTech SE to supply the vaccines.

Wu said that with the help of the German government negotiations with BioNTech were still underway.

However, he warned of China’s clout over coronavirus vaccine supplies, saying vaccine diplomacy “gives the Chinese government an opportunity to exert its influence in the Western hemisphere.”
