BEIJING, Jan 7 (Reuters) – China’s foreign exchange reserves rose slightly less than expected in December, official data showed on Wednesday, as the dollar weakness persisted.

The country’s foreign exchange reserves, the world’s largest, increased by $11.5 billion last month to $3.358 trillion, against a Reuters poll forecast of $3.36 trillion. The reserves totalled $3.346 trillion in November.

The yuan fell 1.22% against the dollar last month, while the dollar weakened 1.23% against a basket of other major currencies.
