Afterwards, Wu would be a constant threat to the state of Chu on its southeastern flank until its demise.

Wu curried relationships with Chu's vassals in the Yangtze river region to weaken support for Chu.

In 506 BC, Wu launched a surprise attack and occupied the capital of Chu.

Afterwards, Wu was briefly the most powerful nation, and turned to other campaigns, defeating the State of Qi in 484 BC.
