One of our company 737's was inbound to Taipei visually when the crew were astonished to see two F5 fighters seemingly climbing vertically very close and through the Boeing's altitude. The crew queried Taipei ATC saying it was a near miss and no warning from ATC.
ATC replied there was no problem as the F5's were on a VFR clearance. Not my personal experience but thought I would toss it in for good measure
