Narrative:

Aircraft X was under radar advisories. Aircraft X was issued VFR traffic at his altitude south bound; and told their current heading they would go behind the traffic. I then told them if they turned 15 degrees to the right that they would definitely go behind. Aircraft X acknowledged with looking for traffic. I was then up for break; and during the relief briefing aircraft X told me that traffic had come within 20 feet of him. That is when I noticed aircraft X had turned left and reversed course back around into the traffic. I then reported the event to the OM.I should have re issued the traffic again to make sure they saw them and/or given a control instruction instead of a suggested heading.
