Singapore (AP) - Singapore said Monday it was no longer concerned about Genting International's business integrity after the casino operator took measures to clear its links to a Macau tycoon. Malaysia-based Genting, which held a groundbreaking ceremony Monday for its 5.2 billion Singapore dollars (USD 3.4 billion, EUR 2.5 billion) casino project, was warned by Singapore in February that the company and its associates would have to prove they could run a clean gambling venue.
