U.S. Secretary of State Hillary Clinton will promote "tax fairness" at a meeting next week in Paris of the Organization for Economic Cooperation and Development (OECD), a senior U.S. diplomat said Tuesday. Richard Hormats, the undersecretary of state for economic, energy, and agricultural affairs, said Clinton will discuss "tax fairness, accountability, how countries structure their tax systems." According to Hormats, the point is to ensure that tax systems provide "sufficient revenues to finance development, that the responsibility for providing these revenues is fairly shared among taxpayers, and that the use of the revenue is transparent." Clinton will lead the U.S. delegation to the Paris headquarters of the 34-country OECD, which promotes economic and social policies worldwide, when it celebrates its 50th anniversary next week. French President Nicolas Sarkozy, German Chancellor Angela Merkel, and Japanese Prime Minister Naoto Kan also will attend.
