The Biden administration wants to start moving weapons and equipment into Ukraine within days of the anticipated passage this week of legislation that includes US$60 billion in military aid to Kyiv.

Officials and experts agree that the artillery rounds, precision-guided missiles and air defenses will change the military outlook for Ukraine. But RTHK's Moscow correspondent, Fred Weir, told Annemarie Evans that the aid would not be a game-changer in the war, but would just prolong it:
