china is much worse in that regard. i was never subjected to it, but i could observe it. lot's of drinking.generally business decisions aren't made until after a big dinner with everyone with lots of alcohol. not everyone does it though, but it is considered normal and sometimes expected. they may not pressure anyone to drink, but it could affect their decisions later.
In US the only time I even heard of any kind of peer pressure was from first year college kids, who have not yet had a chance to explore their new found lack of parental supervision.
