 From VOA Learning English, this is the economics report. Many ties joined protests in Bangkok last year. They urged Prime Minister Yingluk Shenawat to deal with the growing problem of corruption in their country. How much economic activity is lost to corruption is difficult to estimate. The University of the Thai Chamber of Commerce studied the issue not too long ago. The university found that more than 2% of all of the goods and services produced in Thailand or worth about $11 billion will likely be lost to corruption this year. According to the researchers, many business people say they are paying more to Thai officials and politicians to win government contracts. Political economist Pasuk Panchaychit says there is evidence that officials are making progress in controlling low-level corruption. But, she says, the slowing world economy means growing competition for profitable deals with the government. Bondit Nichata Wan is a former central bank official and president of the Thai Institute of Directors. He says corruption in Thailand appears to be more of a problem now than it was 10 years ago. And the problem affects more than Thailand. The American-based Center for International Policy says that more than $2.7 trillion in illegal funds left China between 2001 and 2010. The money left as a result of criminal financial deals, corruption, tax evasion or other illegal activities. For Thailand, the amount was $64 billion during the same period. In 2003, the United Nations passed a convention against corruption, but observers say the fight against corruption needs to go beyond law enforcement. They say it must include non-governmental organizations and private industry groups. For VOA Learning English, I'm Laurel Bowman.
