ELI5: When sitting at the UN (or any gathering of nations) how do countries who do not recognise each other interact? I.e not all countries recognise Taiwan.

There is plenty of room to just ignore a diplomatic delegation to a conference. You do not have to speak to them directly or mention them at all. If they are the subject of the topic you can call it by the status you recognize and everyone will understand. Diplomats are very good at ignoring the elephant in the room and step carefully around it.

In private meetings and parties though words do flow more freely. This is where the diplomacy is more practical so there are less room for the principles of not recognizing a country. These private meetings are not publicly recorded and it is understood that what is being said is not to be taken out of context.
