China's new president Xi Jinping heads to Africa as his country's influence on the continent soars, but with its big money is provoking resentment.

In a second day of bluster following a landmark disarmament accord, North Korea on Wednesday threatened retaliation if the United States carries out what the North claims are plans to annihilate it in a nuclear attack. At six-nation talks in Beijing on Monday, North Korea had promised to give up its nuclear-weapons programme.

The chief of the World Bank took a hard line on corruption on Friday while his counterpart at the International Monetary Fund said policy-makers need to be ready to adapt to a more difficult economic environment in the coming year as delegates gathered for the sister institutions' annual meetings.
