China coach Alain Perrin called for goal-line technology to be introduced to the Asian Cup after his side had an apparent goal disallowed against North Korea on Sunday.
On the stroke of half-time, with China 2-0 up, midfielder Yu Hai played a delicate chip over North Korean goalkeeper Ri Myong-Guk that appeared set for the back of the net.
But defender Jon Kwang-Ik scrambled back and headed it away. Slow-motion television replays were not conclusive but appeared to show the ball cross the line.
"We have the benefit of this advanced technology and I hope it comes to the Asian Cup like it is at the World Cup," Perrin told reporters after China's 2-1 win.
"It is very helpful for referees and if in the future we can have this technology at the Asian Cup it would be very good."
Goal-line technology was used for the first time at the World Cup last summer in Brazil and features in England's Premier League.
Last month Germany's top-flight voted to introduce the camera-based Hawk-Eye system, which notifies the referee if the ball has crossed the goal-line, for the 2015/16 season.
China made it three victories from three matches with Sunday's win over North Korea in Canberra. Midfielder Sun Ke scored both goals with Chinese striker Gao Lin contributing an own goal.
