Kerry urges 'fresh thinking' to tackle global woes
US secretary of state nominee John Kerry has called for "fresh thinking" as he outlined his foreign policy agenda and plans for relations with Iran, China and the Middle East.
Speaking to the Senate Foreign Relations Committee, he said US foreign policy is also about aid, and food security.
Mr Kerry was nominated last month by President Barack Obama to take over from Hillary Clinton.
During his almost four-hour hearing, he laid out his thoughts on some of the world's top challenges in a measured, non-confrontational way.
