Yuan heads for three months high amid band-widening signals

China's Yuan was set for the biggest weekly appreciation in three months as the central bank showed plans to expand a trading band that's been limiting advance since October. The currency gained 0.21% and reached 6.1792 per greenback.

Official data indicates that due to massive capital inflow, China's foreign-exchange reserves, which are the largest in the whole world, climbed by $128 billion to a peak of $3.44 trillion in the first three months of this year.
