US President Barack Obama arrives in the Philippines shortly on the final leg of his Asia tour, as the two sides signed a military co-operation deal.

The accord, signed in Manila, allows a bigger US military presence in the South East Asian nation.

It comes with Manila embroiled in a bitter territorial dispute with Beijing over parts of the South China Sea.
