The Denver 9 Controller had two aircraft (Aircraft X and Aircraft Y) on converging courses at the same altitude (FL370). If the D side from ZMP sector 42 wouldn't have the called Denver 9 Controller to turn Aircraft X 20 left; separation would have been lost less than 5 miles inside of our airspace. Both aircraft were less than 2 minutes from the boundary when we initiated the call to ZDV. With the 20 degree left turn; the aircraft passed approximately 6 mile from each other at the same altitude and within 5 miles inside our boundary! Unbelievable!
ZMP ARTCC Controller reported the adjacent center sector handed off two aircraft to them on converging headings at the same altitude.
