Danny Wilson’s men put in a superb performance, crossing the whitewash six times, but the day belonged to the Newport Gwent Dragons contingent with four of the tries coming from four Men of Gwent.
Hallam Amos and Jack Dixon went over in the first half with Swansea based outside half, Sam Davies adding a further eight points with his boot, while Samoa were limited to a solitary penalty from Fomai Ah Ki.
A tiring Samoa conceded a further four tries after the break with half of these coming from Dragons players Elliott Dee and Ieuan Jones.
A great start for Wales with the Dragons contingent laying down sizable markers.
It’s an all Celtic clash next when Wales face Scotland on Sunday 9 June
