President-elect Donald Trump's daughter Ivanka sat in on his first face-to-face meeting with a foreign leader, Japanese Prime Minister Shinzo Abe, according to a photo of the impromptu Trump Tower released by the Japanese government.

Her inclusion comes as Trump faces questions about how he plans provide assurances that his vast business empire will be walled off from his dealings in the White House. Ivanka and her husband Jared Kushner, along with Trump's adult sons Donald Jr. and Eric, played major roles in his campaign and have all been named to the executive committee of his transition team.

The Trump Organization said last Friday that it was planning to transfer the management of Trump's businesses to his three oldest children, but has not clarified how. Ethics experts have scoffed at the arrangement as far from satisfactory and in no way a traditional "blind trust," given that Trump would remain the owner and that he is well aware of his holdings.

The presence of Ivanka at the meeting, coming on the heels of reports that a transition staffer had inquired about securing clearances for the Trump children, is likely to provoke fresh concerns about how the incoming president is handling potential conflicts of interest.

The meeting between Trump and Abe lasted roughly 90 minutes, beginning at 4:55 p.m., with Vice President-elect Mike Pence joining in for the tail end, according to the transition team.
