But the biggest rewards - and challenges - could hap if others articulation the club.
China is among those vying to motion up, arsenic is Taiwan.
Could the UK veto China's membership? Or usage its rank to signifier China's entree and ambitions?
The existent prize would beryllium if the US reverses the determination made by President Trump not to motion up.
