BANGKOK, May 23 (Reuters) - Thailand's customs-based exports rose 6.8% in April from a year earlier, the commerce ministry said on Thursday, beating analysts' expectations.

The reading compared with a forecast for a 0.35% year-on-year increase for April in a Reuters poll, and followed March's 10.9% decline.
