HANOI, Sept 25 (Reuters) - A group of international bondholders with 75% of $300 million worth of convertible bonds in Vietnamese developer No Va Land urged the company to negotiate a restructuring agreement, threatening moves that would derail talks with domestic creditors.

"No Va Land's prioritisation of local investors and sidelining of international bondholders is damaging international investors' confidence in Vietnam," the Ad Hoc Group of foreign bondholders, said in a statement on Monday. (Reporting by Phuong Nguyen)
