GUADALAJARA, Mexico - North America's leaders have ended their two-day summit in Guadalajara, Mexico, pledging a united effort on economic recovery, trade, swine flu and climate change.

A statement from Prime Minister Stephen Harper, U.S. President Barack Obama and Mexican President Felipe Calderon says their countries are offering a "joint, responsible and transparent" response to the spreading swine flu threat.

They also discussed the political crisis in Honduras.

Harper came out in defence of the country's ousted president, Manuel Zelaya.

Canada has said the president should be allowed to complete the final months of his elected mandate - and Harper told fellow leaders that the solution to the crisis must include support for constitutional democracy.
