WASHINGTON (Reuters) - U.S. President Joe Biden on Tuesday said it remains to be seen whether Russia follows through with any actions to scale down its military operations in Ukraine, saying Washington and its allies will continue with strong sanctions and aid for Ukraine.

       "We'll see if they follow through with what they're suggesting" as Moscow-Kyiv negotiations continue, he told reporters at the White House following his meeting with Prime Minister Lee Hsien Loong of Singapore. "We're going to continue to keep a close eye on what's going on."
