Essentially countries that were developed prior to 1990 or so , although South Korea is a tricky case today going by this definition, as are Taiwan, Hongkong and Singapore

Yes community refers to whose who participate in community.

How is this hard to understand?

Broadly speaking coast de ivory and the like is not a participant in the international community.

China, Russia, India, Pakistan, Iran, Saudi Arabia, and many many other countries that are very active members of the international community are not counted among members of THE "international community". Hell, much of Europe isn't either, including some of the former colonial empires, on some topics.

China, Russia, India are certainly referred to when using this term. Iran and Saudi Arbia may or may not be. Usually not Pakistan, so I really dont know what in the hell you are saying.

> A similar thing plays out when the term "international community" is used in news. It refers to the US and its major allies which means US, Canada, Western Europe, Japan, Australia and New Zealand more or less.

Wait, really? I thought "international community" meant all countries.

There was a particularly memorable use of this sense some time ago, when the UK representative to the UN explained that they abstained from a vote in the General Council that passed with something like 200+ members voting for it because "the international community is still divided on the topic".

That's because you're reasonable.

Sometimes it's used in the expected way, but (more?) often, "international community" euphemistically refers to whomever is currently one of, or an ally of the above mentioned countries.
