Creditors of Russian billionaire Vladislav Doronin's Aman Resorts Group Ltd., are trying to push the ultra luxurious resort operator favored by rock royalty, Hollywood stars and business tycoons into bankruptcy, Dow Jones Daily Bankruptcy Review reported today. The backers, namely American venture capitalist Omar Amanat, British hedge fund manager George Robinson and resort founder Adrian Zecha, said in court papers filed yesterday that the hotel chain owes them about $70.9 million in unpaid fees.
