The blank report: Vietnamese martial arts and the data classification problem

On January 12, 2026, my work inbox received a 40-page PDF file from the communications department of the Vietnam Martial Arts Federation (VMF). After the cover page with the yellow logo on a blue background, no data table existed. On the final page, there was a short confirmation: "No violations recorded in Q4/2026." On the surface, this is good news. But in 14 years as an investigative sports journalist, I learned a simple rule: a spotlessly clean report is never a product of innocence. It is usually a product of a system that knows how to clean up but does not know how to archive. The context needs to be stated clearly. Vietnam currently has more than 40 registered federations and associations operating in martial arts, ranging from traditional Vietnamese martial arts, Vovinam, and Binh Dinh martial arts to boxing, kickboxing, Muay Thai, and MMA. Eight different state agencies hold management authority over those disciplines; and to this day, no common data standard has been applied. The warning about "unclear classification between traditional martial arts and competitive martial arts" that international analysts raise when examining Vietnam's sports records is not an insult. It is an accurate description of the current state. I began by requesting the roster of fighters with competition licenses from three major cities: Hanoi, Da Nang, and Ho Chi Minh City. Each locality issues a different type of license. Hanoi uses a 9-digit numeric code. Da Nang adds the prefix "DN". Ho Chi Minh City records the martial arts system but omits the weight class. Three different formats for the same management purpose. When we asked VMF about standardization, we received this answer over the phone: "That matters belong to local authorities." One notable number: according to publicly available records from the General Department of Physical Education and Sports, between 2026 and 2026, VMF published only three annual reports in total. The 2026 report did not list the number of doping tests, did not name which laboratory was designated, and did not mention any violation of transfer regulations. For a national sports organization, a report with so little information is more worrying than a report full of errors. Errors can be examined. Emptiness cannot. The picture became clearer when we looked at the money trail. Over the past five years, energy drink brands and legal bookmakers in Cambodia spent nearly 120 billion VND on advertising at domestic martial arts events. But in the financial statements of the three largest tournament organizers, sponsorship revenue accounted for only 15% of the total budget. Where did the rest come from? No declaration appendix was ever published. A clean contract has one page. A dirty contract has an entire appendix. To verify, I sent four data requests to the Department of Physical Education and Sports over six months. We received two responses, both identical in wording: "No consolidated data available yet." That phrasing reminded me of a case I followed in Russia during the 2026 World Cup, when 37 abnormal test samples were placed into a "pending recheck" group and never mentioned again. The only difference is that in Vietnam, test samples have not even been collected in sufficient numbers. The laboratory does not know the athlete's name. That is why I trust it. When I contacted a WADA-accredited laboratory in Bangkok to cross-check samples from three Vietnamese fighters, they replied: "We do not know who they are. We only see sample codes." That anonymity creates reliability. But the problem is that a credible mechanism is operating within an ecosystem missing input data. Look at the biggest stars of Vietnamese martial arts. Nguyen Tran Duy Nhat, the most famous Muay Thai fighter of his generation, has had a career longer than any of his peers. But when I cross-referenced his medical records and testing history from 2026 to now, I noticed that his doping tests only took place at international tournaments, where the host country's federation required them. Domestically, he almost disappears from the monitoring system. Not because he is hiding, but because no system exists detailed enough to make him appear. The ambiguous classification between "traditional martial arts" and "competitive martial arts" is becoming a loophole for potential abuse. A fighter suspended from MMA for a positive test can easily enter a local traditional martial arts tournament while waiting for his suspension to take effect. Each federation keeps its own ban list. No federation shares its list with another. As a result, an athlete found using growth hormone in 2026 was still on the preliminary roster of a national team in a different martial art in 2026. The stadium is clean. The locker room is not. When an official report is published with 40 blank pages, the question should not be "who deleted something". The right question is "what mechanism allows people to turn non-action into a successful report". Here, I found part of the answer in Vietnam's sports management culture: we are used to rewarding silence. There is an alternative view, a counter-intuitive angle that I must acknowledge. VMF defenders could argue that the blank report is evidence of honesty. When there is no money to run doping control stations, when domestic laboratories have not yet reached international standards, then publishing a grand number like "0 violations" is the most honest thing they can do. Cheating requires a bit of imagination and a bit of courage. But incompetence requires nothing. A sports official only needs to sit still, not collect data, not issue procedures, and can legally achieve a 100% clean rate. That silence is not only frightening because it hides the cancer of the industry. It is frightening because it paralyzes the entire system's ability to react when a real scandal occurs. As SEA Games 2027 approaches, as LION Championship continues to expand and attract international sponsors, the question is no longer "is Vietnamese martial arts clean or not". The question is: if an athlete tests positive in 2027, which database will authorities use to verify his history? Who will stand up to explain that no test samples were collected for four consecutive years? And will we trust another blank report?
