President Trump is set to host the leaders of Azerbaijan and Armenia at the White House on Friday to sign a peace deal that would potentially end decades of conflict between the two nations.

Azerbaijan’s president, Ilham Aliyev, and Armenian Prime Minister Nikol Pashinyan will meet with Trump separately and sign bilateral agreements with the United States to boost investments in their respective countries, Trump said.

The three leaders will then gather for a peace ceremony. The extent of the agreement was not immediately clear, but if successful it could bring an end to decades of fighting over disputed regions between the two former Soviet republics.

Multiple news outlets reported that the peace agreement was centered on establishing a transit corridor across the region.

“These two Nations have been at War for many years, resulting in the deaths of thousands of people. Many Leaders have tried to end the War, with no success, until now, thanks to ‘TRUMP,'” Trump posted on Truth Social on Thursday night.

“I am very proud of these courageous Leaders for doing the right thing for the Great People of Armenia and Azerbaijan. It will be a Historic Day for Armenia, Azerbaijan, the United States, and, THE WORLD,” he added.

Trump has touted his efforts to broker regional peace deals around the world during his second term so far, citing his role in easing tensions between India and Pakistan and the Congo and Rwanda. He also secured a pause in fighting between Israel and Iran.

However, he has so far been unable to bring an end to the fighting in Ukraine, something he had pledged on the campaign trail to do before even taking office, and fighting has continued in Gaza, leading to a worsening humanitarian crisis.
