Hong Kong, China, who lost 9-1 to Vietnam on Saturday, were put under heavy pressure from Lebanon in the first half with goalkeeper Wong Tsz Ho forced to make save after save.

Twice, Wong thwarted Mustafa Rhyem's powerful shots before his outstretched leg denied Majd Hamouch with Hong Kong, China's first shot on target coming from Chan Lok Him.

Lebanon's relentless pressure paid off in the 15th minute, Rhyem surged forward and his cross cum shot took a slight deflection off Tsang Tsz Hin and landed in the net.

The second half was a more even affair with Hong Kong, China looking particularly threatening on the counter.

A long throw from Wong in the 25th minute found Ng Wun Sing who shot straight at Joueidi before the Lebanon custodian produced a big stop to push away Yuen Sai Kit's effort four minutes later from another breakaway.

Hong Kong, China's improved display saw them equalising in the 30th minute when Li Ka Chun's kick-in was inadvertently steered into his own goal by Hassan Alame as the East Asian side earned their first point in the group.

It was a barnstorming start from Vietnam as the Southeast Asian side went 3-0 up after only three minutes of play.

Chau Doan Phat steered in Tran Quang Nguyen's kick-in in the first minute before a short corner routine saw Tu Minh Quang teeing Vu Ngoc Anh for the finish two minutes later.

Vu scored the pick of the bunch seconds later, surging through on the left and slamming an unstoppable shot into the roof of the net beyond China PR custodian Song Zechao.

Vietnam's incredible intensity saw them score two more before the half-time break with Nguyen Da Hai firing in the fourth in the 10th minute followed by a smart Nguyen Thinh Phat finish from a superb line breaking pass from Vu.

China PR improved after the break and withstood Vietnam's attack for a good 13 minutes before Thinh Phat swept home Ding Cong Vien's low cross.

As frustration crept in for the hosts, Gu Haitao was shown the red card for a heavy challenge with Thinh Phat completing his hat-trick in the 34th minute.

Paiheiertudahong scored from the penalty spot in the 37th minute with Yimuran Yimamu adding another two minutes later to reduce the deficit for China PR but Vietnam were comfortable winners.
