The [adjacent] Center controller was initiating handoffs on Aircraft X and Aircraft Y to the adjacent Center sector. Both aircraft were eastbound at 33000 feet. The transferring Center controller had 'DV8R' in the fourth line of the data block on Aircraft X. Aircraft X was just north and parallel to Aircraft Y. We noticed that because Aircraft X had clearance to deviate right; he was now on a collision course with Aircraft Y. The receiving Center Controller quickly called and told them to descend Aircraft X to 31000 feet. If this hadn't been done Aircraft X and Aircraft Y would have lost separation on the border of our airspace!This has been going on for 25 plus years! That Center's controllers; nor the Supervisors or the Operations Managers are held accountable for this atrocious negligence! The Supervisors; Area Managers; Quality Assurance and so forth are all aware of these situations and still to this day; nothing has been done.
ZMP Center Controller reports two aircraft were handed off to them on conflicting courses. Reporter stated this is a recurring issue at this particular sector.
