Foreign dignitaries descending on this week’s United Nations General Assembly (UNGA) are looking to take advantage of a choice opportunity to sound out the next leader of the free world, seeking early clues where U.S. foreign policy is heading next.

The most sought-after meeting this week may be an audience with one or both of the candidates running for the White House as attention on the world stage is turning to Vice President Kamala Harris and former President Donald Trump.

Each candidate is looking to cultivate their own diplomatic relationships in the final stretch of the campaign, seizing on this week’s UN meetings as an opportunity for talks that illustrate their divergent worldviews.

So far, only one leader is confirmed to meet both Harris and Trump: Ukraine’s Volodymyr Zelensky, who is making an urgent appeal to both candidates, along with President Joe Biden, for sustained help in combatting Russia’s invasion.

Harris is set to hold talks in Washington with the United Arab Emirates’ president on Monday. And Trump has said he plans to talk this week with India’s prime minister.

On Sunday, Trump wrote on social media that he’d met with Qatari Emir Sheikh Tamim bin Hamad Al Thani and Qatari Prime Minister Mohammed bin Abdulrahman Al-Thani at the former president’s Mar-a-Lago resort in Florida. Qatar has acted as a key intermediary for Hamas in ongoing efforts to reach a hostage and ceasefire agreement in Gaza.
