Chinese Super League: referees to speak into a microphone, with 3D offside planned for 2027

The Chinese Super League spent years trying to fix trust in referees, and got nowhere. Tencent News reports that the full introduction of VAR did not settle the arguments. It created new ones: long waits for a verdict, a referee's gesture with no explanation, and offside calls decided by millimetres that a fan cannot judge alone.

In August and September 2026 the Chinese Football Association and the competition organisers agreed a package of changes. From the 2027 season, Super League matches are to use public announcements of decisions by the referee over the stadium sound system, a solution already tested at some games. At the same time the league says it is working to bring in semi-automated 3D offside.

Where the time saving comes from

The Chinese account gives a concrete figure. In leagues already using such a system, offside verification fell from nearly 70 seconds to a few seconds. The mechanism described in the same text combines several high-speed cameras with an algorithm. It maps the key points of a player's body and generates a dynamic 3D offside line. On the communication side the change is just as simple: instead of "the result only, no reason", the fan gets an explanation straight away.

This is not the first attempt at the subject. In April 2025 Chinese sports media reported that the Super League would not introduce semi-automated offside in the short term. They pointed not at the technology itself but at the conditions around it: whether stadiums meet the installation requirements, whether every corner of the pitch can be covered, how much the equipment costs and how referees are to be trained. There was also the matter of media comment after the referees' committee decision on the Wuhan Three Towns versus Shanghai Shenhua match.

How much equipment it takes

The scale of the investment is clearest against the model set by the FIFA system: twelve dedicated cameras under the stadium roof, tracking up to 29 body points of each player 50 times per second, and a ball with an inertial sensor running 500 times per second. That solution was built for a World Cup, where every stadium met a single technical standard. In a league played at more than a dozen grounds of different ages and roof geometries, that condition is far harder to meet. It is the grounds, not the algorithm, that set the realistic horizon for deployment.

Two years, not two months

Comparing the two accounts gives a realistic timetable. A league that does not yet have the technology installed needs the equipment first, then training, and a transition season at the end. The Premier League, with the best infrastructure in Europe, agreed to the system in April 2024 and only launched it during the season.

The Chinese plan therefore has two layers: the cheaper and more certain one, communication, which can be introduced immediately, and the more expensive one, measurement, which depends on the stadiums. That is a sensible order. A public explanation of a decision improves how it is received even when the referee still makes measurement errors.
