I see. So it’s the same but different.?.
People in the US and elsewhere think it stands out because China is a now a rival. Back in the Cold War, esp from the 60s, all three were on the same side. Nobody bothered to ask where Pakistan got most of its fighters from. Or its tanks, missiles and nuclear technology. Now everyone talks about it as if Pakistan has suddenly embraced China.
So as I said its more visible now since China is viewed as a rival.
