A goal by Nguyen Tien Linh and a brace by Ha Duc Chinh gifted Vietnam a 3-0 lead going into halftime before a second-half own goal by a Cambodian defender made it 4-0 for Park Hang-seo’s side.
Cambodia had a golden chance to score a consolation goal seconds before the final whistle, but keeper Van Toan made a smart save from a penalty kick to help Vietnam maintain a clean sheet.
The last challenge between Vietnam and their long-awaited SEA Games gold medal will be Indonesia who trounced Myanmar 4-2 in the remaining semifinal earlier on the same day.
Both teams started the match at a high tempo, with Cambodia confidently competing for the ball in midfield, thus creating numerous difficulties for Vietnam in deploying their attacks.
However, it was Park Hang-seo’s side who opened the scoring, as Tien Linh met Duc Chinh’s right-wing cross with an unstoppable header to the far corner in the 20th minute.

However, Vietnamese fans had to wait only five more minutes to celebrate the second goal, with Duc Chinh speeding up to take a long pass from Thanh Chung and beating the goalie in a one-on-one to net his sixth goal in this year’s SEA Games.
