Though Biden warned of Chinese challenges across the Indo-Pacific region, the Quad's joint statement did not call Beijing out by name.

President Joe Biden was caught on a hot mic saying China is “testing” the US and its allies in the Indo-Pacific region during a Quad leaders’ summit — even as the bloc’s members in their public remarks sidestepped the idea that they are a counterweight to Chinese influence.

The president warned leaders of Japan, India and Australia that Beijing "continues to act aggressively" during his hometown summit.
