The Chinese President Hu Jintao has arrived in Washington at the start of a four-day visit. He'll meet President Obama on Wednesday. Mr Hu's trip comes at a time of growing tensions between the US and China over trade, monetary and strategic issues. In particular, Washington wants Beijing to do more to allow its currency, the yuan, to rise against the dollar.
A Polish investigation into the plane crash last year in Russia that killed the Polish President Lech Kaczynski and 95 others has accused Russian air traffic controllers of failing to warn the pilots the aircraft was off course. An official Russian inquiry last year said the pilots were under psychological pressure from passengers to land despite the bad weather. Adam Easton reports.
Polish investigators said air traffic controllers, acting under considerable pressure because of the bad weather, made a number of errors as the president's plane approached the military airstrip in dense fog last April. They said at one point the control tower told the pilots the plane was on track when in fact it was well off course. The Russians also gave the crew incorrect weather and visibility information, and a crucial height warning too late, the Polish side said.

Sir John Chilcot said publication of key extracts of the communications between the then British prime minister and US president would have illuminated Mr Blair's position at critical points.
