In 180 BC, Emperor Wen of Han made efforts to appease Zhao. Learning that Zhao's parents were buried in Zhending, he set aside a town close by just to take care of their graves. Zhao's cousins were appointed to high offices at the Han court. He also withdrew the army stationed in Changsha on the Han-Nanyue border. In response, Zhao rescinded his claims to emperorship while communicating with the Han, however he continued using the title of emperor within his kingdom. Tribute bearing envoys from Nanyue were sent to the Han and thus the iron trade was resumed.
