Chicago:  Chicago will host the NATO and G-8 summits in May 2012 to discuss the future of coalition operations in Afghanistan, President Barack Obama said on Thursday.

It is for the first time since 1977 in London that the two organizations are holding meetings in the same city at the same time.

"We'll have to do the hard work of keeping the gains that we've made, while we draw down our forces and transition responsibility to the Afghan government.

"Next May, in Chicago, we will host a summit with our NATO allies and partners to shape the next phase of this transition," President Obama said in his address to the nation from the White House.

"World leaders will discuss the future course of coalition operations in Afghanistan. The US would have drawn down more than 30,000 troops from Afghanistan by the time the summits take place," the US President said.

Barack Obama ordered withdrawal of all 33,000 surge troops from Afghanistan by 2012 as part of his plan to bring soldiers back home early and wind down the decade-long war there.

The withdrawals will see a first group of 10,000 American soldiers brought home from Afghanistan this year and another 23,000 by the end of September 2012.

"By 2014, this process of transition will be complete, and the Afghan people will be responsible for their own security," he said.

Mayor Rahm Emanuel said the two summits will not only help boost the economy of Chicago, the hometown of the US President, but also an opportunity to showcase "why it is a city on the move," a Channel News reported.
