US President Barack Obama heads to London tomorrow for his first overseas trip since taking office, to take part in the economic summit of 20 major and developing nations that together represent more than 85 percent of the global economy.

Advisers said the goal was to manage the current crisis by restoring growth and to prevent a future downturn by reforming financial regulations.

Obama has vowed to listen to his foreign counterparts and lead by example to address the economic crisis and work to stem future financial catastrophes.
