HTX's Hong Kong entity has withdrawn its application to operate as a virtual asset trading platform offering retail trading services, according to the local regulator's website.
The company, also known as Huobi HK, initially submitted its application last week, but withdrew it three days later on February 23, the South China Morning Post has reported.
A spokesperson for HTX has clarified Huobi HK operates separately from the parent company.
Hong Kong's SFC has set February 29 as the deadline for crypto trading platforms to submit their license applications, and those that fail to do so must cease operations in Hong Kong by May 31.
As of last year, the city has implemented a new regulatory framework for virtual assets under which any companies wishing to sell or promote cryptocurrencies to residents of Hong Kong must obtain a license by 29 February.
