The US President Joe Biden said he is confident that the summit with Russian President Vladimir Putin in June.

"I'm confident we'll be able to do it. We don't have any specific time or place. That's being worked on," Biden told reporters in the White House when asked about meeting with Putin in June.

Biden also indicated that the troops at the Russian-Ukrainian border would not change his intention to meet with his Russian counterpart.

"It does not impact my desire to have a one on one meeting ... He (Putin) had more troops (at the border) before. He has withdrawn troops. There are still troops amassed, but significantly less than he had a month ago," he said.

White House Press Secretary Jen Psaki said later in a daily press briefing that the discussions between two sides over the summit's location, timing, and agenda are still underway.
