"If they want to export software to Western Countries they need access to the Western software platforms (windows, osx, android, iOS)"
But the problem for the West is that Western countries comprise a mere one-eighth of the world's market. The West is literally a niche market. The Chinese market ALONE is larger the WHOLE of the West.
The Chinese approach is "Most of the World can use use software which doesn't need access to the Western software platforms (windows, osx, android, iOS)"
The American "World Series" is not, it's just a regional sport.
I guess technically this actually applies to any country, but China's the obvious one where it could vaguely plausibly actually happen one day.
Not basing almost your entire country's IT on Windows also doesn't preclude you participating in the software export market.
