Unless theyre talking about setting up seperate NBA leagues in different countries, I dont see how this would work, namely travel wise, without extending the season.
The only way I could see it work, is if they started SEVERAL teams in europe or china and adding a whole new conference. That way when a team has to travel to europe, theyre there for a couple weeks to play all the teams, then travel back home. Traveling that distance to play one team. Not to mention all the traveling, that one or two teams in europe or china would have to do to play the rest of the league. Mexico City wouldnt be bad I guess.
If this is true, and I doubt it is, it would have to be for seperate NBA leagues in different countries.
Players would throw a fit over this. Players have already refused to report to teams they dont like being traded to. Imagine if a player got traded to China mid season lol
