It's unclear whether President Donald Trump, who vowed not to pursue foreign business deals while in office, plans to actually partake in any of the ventures.
The trademark approvals were first reported Wednesday by The Associated Press.
China has already registered a trademark February 14 to a Trump-branded construction firm after a 10-year legal battle that ended in the president's favor after he launched his GOP campaign.

"When Trump is profiting from these valuable Chinese benefits flowing into him, how can we be sure he will advance USA interests in his engagements with that country, for example by staunching the flow of American jobs out from the U.S.to China?"
That being said, it would be naive to assume Trump would only register trademarks defensively in the counterfeit capital of the world and has no interest in making use of any of them in the future. "Any suggestion to the contrary demonstrates a complete disregard of the facts as well as a lack of understanding of worldwide trademark law, " he said in an email.
