Saipan casino operator Imperial Pacific International (IPI) is suing a VIP gambler for failing to honor a $5m credit marker.

On Wednesday, the Marianas Variety reported that IPI had filed a lawsuit in the Commonwealth of the Northern Mariana Islands (CNMI) Superior Court against Yonglun Bao, a high-roller from China who has proven unwilling or unable to honor his gambling debts.

IPI attorneys told the court that Bao was given an open credit line of up to $20m, of which $5m was dispensed for gambling purposes when Bao visited IPI’s temporary casino Best Sunshine Live in February 2017. IPI’s permanent venue, the Imperial Pacific Resort Hotel Saipan, launched in July of that year.

However, Bao failed to repay the $5m by the due date specified in the promissory note he signed. The note calls for an annual interest rate of 24% and also makes Bao liable for collection agency and legal fees should any lawsuit be required to ensure repayment of the loan.
