Singapore-based KOP Capital, controlled by the emirate-owned Dubai Group, will buy a 50 percent stake in European hotel chain Stein Group for $250 million, and spend about the same amount on new hotels in Asia. "We have always wanted to acquire an international chain of hotels and resorts, and were looking for a product that we felt was missing from the market. Stein looked like a good strategic fit," KOP's managing director Leny Suparman told Reuters in an interview on Wednesday.
