The United States ambassador to Australia has called on the Morrison government to take stronger action against alleged Chinese government political harassment of Australian residents.

Speaking on ABC television, Arthur Culvahouse said Uighurs in Australia were being monitored and followed by agents of the Chinese government and that the Chinese consul-general to Brisbane, Xu Jie, had encouraged the opposition to pro-Hong Kong democracy demonstrators at the University of Queensland.

The ambassador's comments on Thursday morning came just hours after a Queensland University protest leader, Drew Pavlou, met US government officials in Washington, DC, to discuss his concerns about alleged Chinese government harassment in Australia.

Mr Pavlou and his lawyer Mark Tarrant met staff of the Congressional-Executive Commission on China, which monitors human rights in China for Congress, and the US-China Economic and Security Review Commission, which investigates national security and trade issues between the two nations.
