Canadian investor and businessman Kevin O’Leary said Chinese companies should be banned from listing on U.S. stock markets until they play be the same set of rules that apply to domestic firms.

Speaking at the Benzinga Fintech Deal Day & Awards on Monday, O’Leary said: “I can’t litigate in China so they shouldn’t be able to litigate here. I don’t know why we let them list any company on our exchanges cause they’re not compliant with our accounting and transparency. We’ve got to treat China the way they treat us.”
