Vietnamese Martial Arts and the Gap in the Classification Sheet

At a competition night in a Ho Chi Minh City arena, the referee panel had to switch rule sets between two consecutive bouts on the same mat. The first bout was full-contact: a head kick scored only on clear contact, and throws were prohibited. The second was a forms performance: judges scored on technique scale, with no opponent and no contact. One arena, one judging row, two entirely different scoring systems, and no document obliging them to be consistent with each other.

I sat in the seventh row and timed it. The transition took four minutes. Four minutes for one rulebook to yield to another, with no meeting, no minutes, no written note retained. For someone whose work is reading rules, that detail is worth recording more than any beautiful exchange of the night.

Context: three categories, three definitions of victory

Vietnamese martial arts operate across at least three fundamentally different categories. The modern combat category covers boxing, kickboxing, Muay and domestic MMA events. The performance category covers forms, routines and taolu. The traditional category carries ritual elements and its own grading hierarchy. The three do not share a scoring system, do not share a definition of winning, and most importantly do not share a way of keeping records.

One data point belongs on the table: karate entered the Tokyo 2026 Olympic programme with kata and kumite, then was excluded from Paris 2026 under an International Olympic Committee proposal published on 7 December 2026. A system standardised down to its score scale can still be removed from the largest stage by an administrative decision.

Vovinam, founded in 2026 by Nguyen Loc, has a belt system, has combat, has forms, and has appeared in the SEA Games programme when the host nation registered it. But the names of techniques, the scoring method and the criteria for recognising rank have not been gathered into one shared record set.

Three layers of the same problem

The first layer is the unit for measuring victory. Combat is measured in points and knockouts. Performance is measured on a technique scale. Traditional styles are measured by how completely a routine is executed according to each school's criteria. These three measurements are not convertible, yet organisers still place them side by side on one ticket. Spectators buy a ticket for an evening, not for a rule system.

The second layer is the record. Combat leaves bout sheets, strike counts, fight times, all of which can be digitised and compared across years. Forms leave only a judge's scorecard. A forms athlete competing for ten years may accumulate no comparable record at all, while a combat athlete on a losing streak still has data proving progress. The biggest blind spot sits here, and it is not about technique.

The third layer is incentive. Resources follow medals. A discipline admitted to a major games programme gains quotas, funding and salaried coaches. So every federation has a legitimate reason to keep its own definition of what counts as correct rules, because that definition protects its quota. Nobody tears down the fence that feeds them.

Comparison with the Japanese approach

Judo and karate in Japan operate under one federation, one curriculum, one grading scale. When kata was removed from the Olympics, the domestic system did not collapse, because records were kept from club level upward. The Japanese accept losing an international quota in order to preserve internal consistency.

Vietnam is strong at adaptation: adding events per games cycle, changing rules quickly to match international partners, restructuring a tournament within a single season. That flexibility has saved events from cancellation. But it is also what fragments records to the point where each locality keeps its own version of the truth.

Referees do not create errors; they only record what the rules already contain. When rules change without the previous version being kept, the referee becomes the only keeper of the rule's memory, and personal memory cannot be verified.

Contrarian angle: standardisation is not step one

Most voices in the industry argue the only path is standardising to international criteria, importing rules and score scales, then integrating. I do not side with that, at least not as a first step.

The concrete reason: standardising rules without records only creates a new shell while old data remains lost. Karate has a complete international standard and was still removed from an Olympic cycle. Standardisation protects no one from an administrative decision.

I still have to honestly simulate why the standardisation camp thinks otherwise. They have watched generations of athletes with no international events, no scholarships, no injury insurance, teaching extra classes to survive. For them, importing rules is the shortest route to stable income for athletes. That concern is legitimate, and I acknowledge it before rebutting.

The blind spot lies elsewhere. Diversity is treated as weakness when it is an asset no rival possesses. Vovinam keeps forms and combat inside one system, something karate was forced to split into two separate events. If standardisation means cutting away half to fit a frame, we lose precisely what gives us an edge.

The first mistake is not there to be forgotten, but to serve as a benchmark. The period when arenas closed because of the pandemic was one such benchmark. With no spectators and no chanting, it became clear which parts of the system truly ran on rules and which ran on noise. An empty pitch still keeps the same rules; people simply see more clearly when the noise is gone.

A proposal rather than a conclusion

What must be done before discussing standardisation is rebuilding three data layers: an event layer recording bouts and referee decisions, a context layer recording statutes and every rule-change milestone, and an analysis layer recording scoring criteria together with the person accountable. No complex software is needed. What is needed is a regulation obliging every rule change to come with a retained document, even when the change applies only to a provincial tournament.

Alongside that, referee training should include writing justifications for decisions, not only spotting faults. A referee who can explain why a score was given creates data for the next generation, while a referee who only signals creates disputes.

If every competition cycle leaves an old rulebook beside the new one, then in ten years Vietnamese martial arts will hold something money cannot buy: the ability to measure itself. And data stays silent until someone asks the right question.
