The WTO was established in 1995 and is a successor to the General Agreement on Tariffs and Trade (GATT). Every two years the WTO holds a major summit called a ministerial meeting. The next ministerial meeting will be held in Hong Kong in December 2005. Previous meetings took place in Cancn (Mexico) in 2003, Doha (Qatar) in 2001 and Seattle (USA) in 1999.
