"Ivanka Trump's refusal to divest from her business is especially troubling as the Ivanka brand continues to expand its business in foreign countries," Noah Bookbinder, executive director of watchdog group Citizens for Responsibility and Ethics in Washington, said.
"It raises significant questions about corruption, as it invites the possibility that she could be benefiting financially from her position and her father's presidency or that she could be influenced in her policy work by countries' treatment of her business."
As Ivanka Trump and her father have built their global brands, largely through licensing deals, they have pursued trademarks in dozens of countries.
Those global trademarks have drawn the attention of ethics lawyers because they are granted by foreign governments and can confer enormous value. Concerns about political influence have been especially sharp in China, where the courts and bureaucracy are designed to reflect the will of the ruling Communist Party.
Chinese officials have emphasised that all trademark applications are handled in accordance with the law.
"The brand has filed, updated, and rigorously protected its international trademarks over the past several years in the normal course of business, especially in regions where trademark infringement is rampant," Abigail Klem, president of Ivanka Trump's brand, said in an email.
"We have recently seen a surge in trademark filings by unrelated third parties trying to capitalise on the name and it is our responsibility to diligently protect our trademark."
More approvals are likely to come. Online records from China's trademark office indicate that Ivanka Trump's company last applied for trademarks — 17 of them — on March 28, 2017, the day before she took on a formal role at the White House. Those records yesterday showed at least 25 Ivanka Trump trademarks pending review, 36 active marks and eight with provisional approval.
The World Intellectual Property Organisation's brand database also shows that her company, Ivanka Trump Marks LLC, won three trademarks in the Philippines after her father took office. Two of them that cover clothing, including lingerie and baby clothes, were filed on February 8, 2017, and registered in June and November. The third, filed on March 1, 2017, covers clothing and footwear and was registered in July.
