Zhang Qi, 58, who was a top official in the province of Hainan has been sacked.
In addition to the gold, inspectors discovered 268 billion yuan (£30 billion) in suspected bribes on the man's account, according to reports.
He was also thought to have received multiple luxurious villas as perks.
If Mr Zhang's alleged corruption turns out to be true, he would have been richer than Jack Ma, the wealthiest man in China worth $37 billion (£30 billion) according to Forbes.
