It happened in our backyard to, not sovereign risk but instead they called it 'corruption' for political correctness. at the end of the day shareholder still got screwed. Kingsgate fiasco with Thai government and 6 casino operators in Macau always feels hot and cold that Chinese government will not renew or revoke their license for whatever reason they want to use.
