Narrative:
A320 was climbing out of FL320 for FL370. B737 was level at FL360 opposite direction 80 mi. I issued A320 a restr to be level in 25 mi; which the pilot said he would comply with. 3 mins later A320 was again issued a restr to be level in 10 mi; and again the pilot said he would comply. A320 did not make the restr; and was issued a 40 degree left turn to avoid merging targets.
