Is OKX a Chinese company?｜before a government crackdown pushed operations overseas. Crypto.com was founded in Hong Kong, but its headquarters is now in Singapore.OKX, Binance and HTX, formerly Huobi, were founded in China

Could you clarify for me if OKX is indeed a Chinese company? I've heard that it had operations in China initially, but due to government regulations, it relocated its operations overseas. Crypto.com, on the other hand, started in Hong Kong but has since shifted its headquarters to Singapore. Similarly, I understand that OKX, Binance, and HTX (previously known as Huobi) all had their origins in China. Is this correct? And if so, how has the relocation of these companies affected their operations and business models?
