Narrative:
Aircraft X was inbound to laredo airport direct IAF ovose on the rnv 18R at lrd. The aircraft was cleared to maintain 030 ft until established and cleared for the approach. About 5 miles from ovose; my trainee saw traffic with a beacon XXXX maneuvering in the area of ovose at 018 and called traffic to aircraft X. He said targets appear likely to merge. At that point the XXXX code turned [towards] aircraft X and climbed rapidly to 031. I then canceled the approach clearance of aircraft X and turned the aircraft 30 degrees right and issued a traffic alert. Aircraft X then called the unknown aircraft Y in sight; and said that it was a close one. At that point I asked aircraft X if they were time critical; and when learning they were not; I extended the aircraft vectors to make sure the unknown code XXXX would not be an issue again. Laredo tower was not in communication with aircraft Y; and when he finally did go to laredo to land; I had the tower give that aircraft our phone number to call. Aircraft X company called the supervisor and told him that aircraft Y was less than 200 ft from him same altitude; and that the pilot didn't see aircraft Y until he started the turn and banked away from it.I strongly insist that if there are border aircraft near or in the vicinity of lrd; that they monitor the frequency and let us know they are there. That way this situation won't happen.
