In a physically draining tie, Nguyen Thi Bich Thuy scored the winner after Su Hy-Ysuan had canceled out Chuong Thi Kieu's first half opener as Vietnam confirmed their berth at Australia/New Zealand 2023.
The triumph completed a remarkable journey as Vietnam overcame a COVID-19 outbreak prior to the AFC Women's Asian Cup India 2022™️ to book their place in the FIFA Women's World Cup.
Defeat for Chinese Taipei means they join Thailand in the Inter-Confederation Playoffs where a win will take them into their first FIFA Women's World Cup in 31 years.
Having beaten Thailand 3-0 on Friday, Chinese Taipei entered the tie only needing a draw with Vietnam having defeated their Southeast Asian rivals 2-0 in their encounter on Wednesday.
That played a part in Vietnam's aggressive start as they immediately dominated possession, forcing Chinese Taipei to defend deep.
The East Asian side found Vietnam's crosses hard to deal with and it cost them as early as the seventh minute as Chuong rose almost unchallenged to nod home Nguyen Thi Tuyet Dung's corner.
Buoyed by the goal, Vietnam pressed forward but it nearly proved to be their undoing in the 19th minute when Su Hy-Ysuan latched onto a loose ball and raced into the penalty box before relaying it to a surging Chen Yen-Ping.
Chen slotted home but to Chinese Taipei's dismay, the ball had crossed the touchline before Su had played it back.
Neither side found a way through in the remaining minutes of the first half but Chinese Taipei started the second in spectacular fashion as Su drew them level in the 49th minute.
The goal was the result of Wu Kai-Ching's brilliance as the midfielder stole the ball, weaved past several Vietnam players and released Su who sent her shot into the bottom left corner past goalkeeper Tran Thi Kim Thanh.
The match had shifted in Chinese Taipei's favour but Vietnam were undaunted and pushed forward with their positive play rewarded with a second goal in the 56th minute as Nguyen Thi Bich Thuy brilliantly controlled Thai Thi Thao's cross before blasting the ball past Tsai Ming-Jung.
That was enough to take Vietnam to a historic first appearance at the FIFA Women's World Cup.
