TAIPEI—Taiwan’s diplomatic isolation will diminish as foreign governments look to the island for a model of how democracies can stand up to Beijing, Foreign Minister Joseph Wu predicted, amid an international backlash against China’s assertive foreign policy.

Mr. Wu, the chief diplomat for the democratically self-governed island that Beijing claims as its territory, said in an interview Wednesday that the U.S. and governments in Europe are increasingly looking at how Taiwan manages pressure from China’s ruling Communist Party.

“Taiwan has been under this kind of influence operations for decades,” Mr. Wu said, referring to Beijing’s efforts to rally international support for its own interests.

Beijing in recent years has been accused by the U.S. and other Western countries of using its market clout to gain influence in smaller nations, and in some cases of using more hard-edge methods to get its way.

Now that Western countries have experienced in recent months what Mr. Wu called an awakening over China’s methods, “they are willing to engage Taiwan, willing to exchange experiences with Taiwan, and to learn from Taiwan,” he said.
