MOSCOW, June 27 (Xinhua) -- Russian President Vladimir Putin and U.S. President Donald Trump will meet in a third country, with the date and venue to be announced Thursday, Kremlin aide Yuri Ushakov said Wednesday.

Ushakov met with reporters following Putin's closed-door meeting with visiting U.S. National Security Advisor John Bolton at the Kremlin.

The Kremlin aide said the details of the forthcoming Putin-Trump summit were discussed and "a very convenient place has been chosen for us and for the U.S. side."

Ushakov said the summit may last several hours with the two presidents first meeting tete-a-tete in the middle of the day and then together with delegations.

"They could agree on a joint statement outlining further steps from both sides to improve bilateral relations and joint actions in the international arena to ensure global stability and security," he said.

Ushakov said Putin discussed with Bolton priority issues that the presidents will address at the upcoming summit, in particular the Syria issue and its humanitarian aspect.

Putin reiterated that Moscow did not interfere in the 2016 U.S. elections. Both sides discussed the Ukrainian settlement, but they did not mention the current U.S. sanctions against Russia.

Earlier in the day, Bolton met with Russian Foreign Minister Sergei Lavrov and representatives of the Russian Security Council.
