Narrative:
A319 given climb to FL330 up to FL260. LR60 given climb to FL250; read back up to FL350 shipped to next sector. Noticed LR60 up through FL250; tried to turn A319 30 degrees; no response. Supplemental information from acn 723015: LR60 read back the wrong altitude and ATC observed the climb. A319 took 2 xmissions to turn to avoid the LR60.
