Washington: US President Barack Obama will continue to give priority to building ties with emerging powers like India, China and Brazil for rebalancing US foreign policy in his second term too.

"It's not related" to a second term, Obama's press secretary Jay Carney said, citing President's National Security Advisor Tom Donilon about the approach that the Obama took when he took office in January 2009.

He said, “To rebalance US priorities in foreign policy, Obama  has taken into account the emergence of countries like China and India and Brazil, and not to focus solely on one or two regions,".

Carney said, "More broadly, I think also that he came in determined to re-establish America's leadership-America's standing in the world-and feels that great progress has been made in that regard as well."

He said, “In a little over two years that he has been in office, Obama has taken enormous steps towards overcoming a lot of challenges, principally the economic ones, but also rebalancing our foreign policy and re-establishing American leadership around the world."

The White House spokesman was asked about Obama's second term priorities after the president launched his bid for re-election with a short video on BarackObama.com using what apparently will be one of his campaign slogans, "It begins with us."

Obama also sent an e-mail to supporters before officially filing papers for the November 2012 election with the Federal Election Commission.

"We've always known that lasting change wouldn't come quickly or easily. It never does. But as my administration and folks across the country fight to protect the progress we've made - and make more - we also need to begin mobilising for 2012, long before the time comes for me to begin campaigning in earnest," Obama said in his e-mail message.
