Taiwan held off a spirited Thailand to win the Asian Hopman Cup mixed team event on Sunday and earn a place in next month's tournament proper in Perth.

Lu Yen-hsun and Hsieh Su-wei sealed victory with a commanding performance in the deciding doubles match, hammering Thai pairing Danai Udomchoke and Tamarine Tanasugarn 6-4, 6-0 to complete the line-up for the eight-nation Hopman Cup.

"We're so happy to win, it's not easy to come here, play all these matches," Lu said.

Hsieh gave Taiwan the early advantage, dictating the opening match with Tamarine to win 6-3, 7-5.

In the men's singles, Danai beat Lu 7-6, 6-4 to bring it to 1-1 overall, edging ahead in a tight but entertaining match against the Asian No 2.
