Narrative:

As we were climbing; about 3000 ft from level off; ATC called out an aircraft at our 4 o'clock position that was converging and 1000 feet above our level off altitude. I called the traffic in sight; and told the captain that this aircraft will be only 1000 feet above our level off altitude. Captain said ok. We were about 2100 feet to level off; plane on autopilot climbing at 2000 feet per minute. After the altitude captured; the captain tried to engage vertical speed (vs) to decrease our climb rate; but vs does not engage during altitude capture mode. Because of the high climb rate; we got a TA and then a RA from the TCAS as the autopilot was leveling off already. The RA commanded a level off; which the autopilot was doing. Therefore; no other action was taken.I am not sure if the captain heard my warning about the other plane being only 1000 feet above our level off altitude; but the other traffic was visible on TCAS. I am not sure why he didn't intervene with vs to reduce our climb rate during the last 1000 feet of our assigned climb; and when he intervened; it was too late since the autopilot had captured our assigned cruise altitude. There was no altitude deviation; or other intervention on the part of the crew. It was just a normal autopilot level off from a normal climb of about 2000 feet per minute. There was no overshoot.awareness and diligence. Our procedures call for reducing climb rate to 1000 feet per minute if another aircraft is within 5 miles and 2000 feet vertically. Our traffic was inside that range.

Title: A light B767-300 flight crew climbing to FL310 was advised of traffic at FL320 but activated the TCAS TA and RA as the autopilot began leveling the rapidly climbing aircraft.
