Advertising, Advertising, Advertising
plus location, communication, publicity, [and a nitch/gimmick does not hurt either]
But, your target customers need to know you exist, what your about [good service, convenience, glamor, party transport, what?] So, if you target Chinese business men, you would want to tailor your ads to them. Chinese letters/words, a commitment to elegance and style [possibly confidentiality], and display in locations where Chinese businessmen will be like popular international airports.
You should plan to maintain your advertisements in your budget, because the best ads will get you more business.
