The Russian military appears to be readying for a renewed push to claim the part of the eastern Donetsk region that remains under Ukraine's control, as well as possible offensives in other sectors.
NIA sources said the six Ukrainians and one American were involved in transporting large consignments of drones from Europe into Myanmar through India.
The meeting comes days after the US temporarily waived some Russian oil sanctions in a bid to ease pressure on global supplies triggered by the war in the Middle East.
