NEW YORK (Reuters) - Blind Chinese dissident Chen Guangcheng arrived in the United States on Saturday after China allowed him to leave a hospital in Beijing in a move that could signal the end of a diplomatic rift between the two countries.

A summit of the G8 leading industrialized nations came down solidly in favor of a push to balance European austerity - an approach long driven by German Chancellor Angela Merkel - with a new dose of U.S.-style stimulus seen as vital to healing ailing euro-zone economies.

BELGRADE (Reuters) - Pro-Western Boris Tadic will bid on Sunday for another five years as Serbia's president and the right to lead the nation into EU membership talks, challenged by rightist Tomislav Nikolic who has threatened to contest the result in the streets. Tadic is tipped to defeat Nikolic in the presidential election for the third time since 2004 as Serbia slowly sheds the legacy of a decade of war and isolation under late strongman Slobodan Milosevic.
