GENEVA, Feb. 17 (Xinhua) -- A new round of trilateral talks among Ukraine, the United States and Russia began in Geneva on Tuesday.

The two-day negotiations, held behind closed doors, are expected to address territorial issues, military matters, political and economic concerns, as well as security arrangements, Russia's state news agency TASS reported.

Russia's delegation includes presidential aide Vladimir Medinsky, Deputy Foreign Minister Mikhail Galuzin and other officials, the Kremlin confirmed on Monday.

The United States is represented by presidential envoy Steve Witkoff and Jared Kushner, son-in-law of the U.S. president. Ukraine's delegation is led by National Security and Defense Council Secretary Rustem Umerov.

"Security and humanitarian issues are on the agenda," Umerov said in a post on his Facebook page on Tuesday.

Two previous rounds of trilateral talks, held in Abu Dhabi on Jan. 23-24 and Feb. 4-5 this year, focused on potential disengagement between Russian and Ukrainian forces, ceasefire monitoring mechanisms and the establishment of a coordination center, but did not resolve key territorial issues.
