Following their 0-0 draw against Singapore two days earlier, Indonesia found it hard going against the 2016 runners-up.
“I would not say that it was an easy match. Indonesia have certainly improved from the last time we played them,” said Vietnam team manager Duong Vu Lam.
“It was quite a hard game, but the players certainly would have learnt some things from this.”
Just two minutes in, a clever cutback from Nguyen Thi Tuyet Dung allowed Huynh Nhu to blast the ball in for the lead.
Nguyen Thi Van fired in from distance in the 28th minute for the second goal and Pham Hai Yen made it 3-0 when her effort was totally misread by Indonesian keeper Norfiince Boma.
Vietnam needed only four minutes after the break to add to the scoreline with Thai Thi Thao scoring from the edge of the box while a melee three minutes later allowed Huynh Nhu to stab home for her second of the match.
Vietnam they finished an easy afternoon with the sixth goal of the game from Nguyen Thi Tuyet Dung.
Philippines picked up their first three points when they beat Singapore 3-0.
The Philippines, who fell to a 4-0 defeat against Myanmar two days ago, put up a more determined performance to open the Singapore defence.
Joyce Semacio broke the deadlock in the eighth minute when she raced past the Singapore defence to score.
“We were not playing well in the first half. We were rushing things,” said Philippines head coach Letecia Bautista afterwards.
“For the next game (against Vietnam), we need to have more control and keep our composure.”
With just one goal from the first half, the Philippines were determined to add to the score line after the break and after numerous close calls, they finally widened their lead though an own goal.
A cross from Philippines’ Kyla Inquig down the right in the 61st minute was turned into goal by Singapore defender Nur Umairah Hamdan.
Seven minutes later, the Philippines made sure of the points when Quinley Quezada swung in a shot from the right that had Singapore custodian Noor Kusumawati Mohamad Rosman well beaten.
