At the proposal of the United States, the United Nations Economic and Social Committee adopted a resolution, in February 1946, calling for a conference to draft a charter for an International Trade Organization (ITO). Seven rounds of negotiations occurred under GATT before the eighth round—the Uruguay Round —concluded in 1994 with the establishment of the World Trade Organization (WTO) as the GATT's replacement. It’s been a busy few weeks for the half-dozen or so companies licensed to charter flights between the United States and Cuba. In December, President Barack Obama announced the restoration of diplomatic relations with Cuba, and the easing of travel and trade restrictions started in mid-January. A Tampa International Airport spokeswoman says that she expects charter operators there to add additional flights to Cuba in the coming weeks, and that GoToCuba.org, a website the airport created to provide Cuba travel information, has seen 1,580 percent more traffic since before Obama’s announcement in December. This led to the Uruguay Round, and ultimately to the WTO. GATT: provisional for almost half a century back to top.

The city of Havana was founded by the Spanish in the 16th century and due to its strategic location it served as a springboard for the Spanish conquest of the continent becoming a stopping point for the treasure-laden Spanish galleons on the crossing between the New World and the Old World. Contemporary Havana can essentially be described as three cities in one: Old Havana, Vedado and the newer suburban districts. The city is the center of the Cuban government, and home to various ministries, headquarters of businesses and over 90 diplomatic offices. Jackson Vetoes Re-Charter of the Second Bank of the US. Andrew Jackson vetoed the bill re-chartering the Second Bank in July 1832 by arguing that in the form presented to him it was incompatible with “justice,” “sound policy” and the Constitution.
