India won the ICC World Twenty20 in South Africa in September 2007
The ICC multi-nation tournament scheduled for the West Indies in 2010 has been shortened from a Champions Trophy to be another World Twenty20.
It will be the third such tournament since the very successful first event in South Africa in September 2007.
The decision has been taken because this year's 50-over-a-side Champions Trophy has been postponed by 12 months due to security worries in Pakistan.
The second ICC World Twenty20 takes place in England next June.
ICC chief executive Haroon Lorgat said: "Although the World Twenty20 is to be held every second year, we decided to hold two on the trot to set the calendar right and ensure a better spread of tournaments."
FUTURE ICC TOURNAMENTS
June 2009: World Twenty20, England
September-October 2009: Champions Trophy, Pakistan
April-May 2010: World Twenty20, West Indies
2011: World Cup, South Asia
The event, scheduled to be held from 23 April 23 to 9 May, will be staged at three venues to be chosen by the ICC in January 2009 following nominations from the West Indies Cricket Board.
"With the ICC Champions Trophy being the final major ICC event of 2009, and the ICC Cricket World Cup being the 50-over event in 2011, it makes perfect sense to have a tournament of a different format in between," Lorgat said.
