In its latest effort to defuse a major public relations problem that might have loomed over Donald J. Trump’s presidency, the Trump Organization on Wednesday announced union accords at two major hotel holdings.

The agreements resolve labor disputes that could have posed a conflict of interest for the president-elect and come on the heels of other similar moves in recent weeks. In November, Mr. Trump paid $25 million to settle a number of lawsuits surrounding fraud allegations at Trump University, his former for-profit education business, and this month the Trump Organization extricated itself from the management of a hotel project in Brazil, where the authorities were investigating allegations of corruption.

Taken together, the moves suggest that Mr. Trump is sensitive to at least the perception that his business dealings could cast a shadow over his presidency, even if he has yet to detail how he might seek a more comprehensive solution to potential conflicts, such as outright divestment.

“On the one hand, I think it’s important to acknowledge that this is meaningful, it does matter,” Danielle Brian, the executive director of the Project on Government Oversight, a nonpartisan ethics watchdog group, said of Wednesday’s agreements. “However, this piecemeal approach to dealing with conflicts is not going to deal with the bigger looming problem.”
