While pushing back Flight minutes earlier from departure time; everything done safe; walk around; load the aircraft. I kept my eyesight on the left side wing walker; my main concern is to make sure that my left wing is clear from touching another wing next door; let me remind you that my right side wing was clear. I continue pushing because my left side wing walker continue giving me the all clear sign; while I was pushing I always kept my sight on my left side wing walker; again my wing walker kept on all clear sign and then I noticed that my flight clip the wing on the other aircraft parked by [Gate X]; then my left side wing walker gave me the stop sign; after my flight hit the wing on the aircraft parked by [Gate X]. Then I moved back the aircraft for repositioning; my supervisor came; mechanics came; and I told the captain to set brakes until further notice. After that I got off from push back; my right side wing walker tow in the plane to [Gate Y]; then I walked to write my statement.
A Pushback Tug Driver reported his push aircraft's right wing struck a parked aircraft during a night push even as his Wing Walker indicated it was clear.
