Pelosi’s Taiwan Visit Threatens China-Australia Reset

SYDNEY—China’s ambassador to Australia said relations between the two countries are at a critical juncture and that the U.S. ally must approach the Taiwan issue cautiously, another example of how House Speaker Nancy Pelosi’s visit to Taipei has raised tensions in the region.

The center-left government led by Australian Prime Minister Anthony Albanese, whose Labor Party came to power after an election in May, has sought a less-confrontational tone with China, a major trading partner that buys much of Australia’s iron ore. Top-level contacts, suspended after Australia’s previous right-leaning government took a hard line on China, recently resumed, including meetings between the defense ministers and foreign ministers of both countries.
