The match between U.23 Thailand and U.23 Cambodia was officiated by main referee Ngo Duy Lan (Vietnamese). This was a decisive match for the ticket to the semi-finals of the 2023 Southeast Asian U.23 tournament, because U.23 Cambodia still had a chance to continue, so they entered the match with determination.

U.23 Cambodia showed that they are not an easy team to bully. Against a highly rated opponent, the team from the land of pagodas launched confident attacks and caused trouble for the home team U.23 Thailand many times. The match was quite balanced in the first 45 minutes of the match, when the "War Elephants" also had opportunities but could not take advantage of them.

In the second half, U.23 Thailand started to "warm up" and poured their squad into the attack. However, when the "War Elephants"' efforts had not yet materialized, the Cambodian players helped the home team score the opening goal. In the 50th minute, a defender of U.23 Cambodia headed the ball back but the home team's goalkeeper was surprised and let the ball go into the net, helping U.23 Thailand take a 1-0 lead.

After that, U.23 Thailand continued to dominate and scored another goal before the match ended. In the 80th minute, Nethithorn Kaewcharoen's shot hit the opponent's foot and changed direction, flying into the U.23 Cambodia net. This was also the goal that sealed the 2-0 victory for U.23 Thailand over U.23 Cambodia.

With this result, U.23 Thailand took the top spot in Group A and became the first team to officially advance to the semi-finals of the 2023 Southeast Asian U.23 tournament. Meanwhile, in the match at the same time, U.23 Myanmar beat U.23 Brunei 4-1. Thus, in Group A, U.23 Cambodia, U.23 Myanmar and U.23 Brunei all stopped after the group stage.

Let me explain further. In Group A, U.23 Thailand ranked first with 6 points, U.23 Cambodia ranked second with 4 points (goal difference +3), U.23 Myanmar ranked third with 4 points (goal difference 0), U.23 Brunei was last (0 points). Because Group A has 4 teams, the results between the second-placed team and the last-placed team will not be counted to ensure fairness with groups with 3 teams (groups B and C). Because U.23 Cambodia previously beat U.23 Brunei 5-0, the team from the land of pagodas only had 1 point. Meanwhile, in Group B, U.23 Indonesia finished the group stage with 3 points. Therefore, U.23 Cambodia has officially stopped.
