Pay to whom?
He was not really betting in a casino or sports book or online.
He was just publicly saying he would bet $5000 that xxx would win etc. That's not a legal wager.
A true gentleman honors his gambling debts -- legal or not.
"Passionate about Pacquiao, Hun Sen, the Prime Minister of Cambodia, is now refusing to pay up on a $5,000 bet he made, believing the fight wasn't judged fairly."
The Prime Minister of Cambodia would not have have bet with a "bookie" and I have mentioned before, has his hands in Nagaworld which has a sportsbook. This book, while Mr. Sen may have some sort of credit account, is linked to an online full service sportsbook. If Mr. Sen decided he wasn't going to pay, Nagaworld would simply pay it for him or already has via their online account. It's not rocket science and $5000.usd is nothing in the world of Prime Ministers like Mr. Hun Sen. He's big money, don't be fooled, so is Nagaworld.
