The rest of the world isn't like the U.S. or Canada. Like the rest of the civilised world, TPE has sterile transit, at least for the terminal that CI and KL use. I did a same a/c turnaround there in January. Was off the a/c, through security and back to departure airside in 2 minutes (helped that the transfer point was adjacent to the gate) so I had time to go to the lounge despite a <50 minute turnaround.
