SEOUL, Dec 1 (Reuters) - South Korean exports in November rose for the first time in 13 months as Asia's economies continued to build up steam, but analysts said a more sustainable recovery still hinged on demand in the region's major Western markets.

Exports in November rose 18.8 percent from a year earlier, the Ministry of Knowledge Economy said on Tuesday, although the headline figure was below market expectations as demand from advanced economies remained depressed.
