Zhu's comments came shortly before Republican presidential candidate Donald Trump lambasted China again, this time for what he said was "devastating currency manipulation."
Trump has employed anti-China rhetoric throughout his campaign, but ramped up his criticism in his high-profile speech at the Republican National Convention in Cleveland, Ohio, on Thursday night local time.
"We are going to enforce all trade violations against any country that cheats," Trump told a cheering crowd of supporters.
"This includes stopping China's outrageous theft of intellectual property, along with their illegal product dumping, and their devastating currency manipulation. They are the greatest that ever came about, they are the greatest currency manipulators ever."
In fact, China's currency had steadily appreciated against the dollar over the past decade, although it recently lost some value against the greenback as the U.S. currency strengthened against almost every other major currency.
