SHANGHAI (Reuters) - China's foreign exchange reserves rose more than expected in September, official data showed on Monday, as the dollar weakened against other major currencies.

The country's foreign exchange reserves - the world's largest - grew by $60 billion to $3.316 trillion last month, compared with a median estimate of $3.304 trillion in a Reuters poll of analysts, and $3.256 trillion in August.

The yuan strengthened about 1.1% against the dollar in September, while the dollar last month weakened around 1% against a basket of other major currencies.
