Coach Nguyen Thanh Tai said: "At this year's World Judo Championships, strong teams were concentrated in Europe, making the competition for medals very fierce.
"However, thanks to careful preparation, Vietnamese athletes are gradually catching up with the global standard. The achievements at this tournament reflect the effectiveness of our efforts to develop judo in Vietnam after a period of investment and growth."
The world championships featured 282 athletes, 196 men and 86 women, from 32 countries and territories, competing in five championship events and five U23 events.
Vietnam sent a delegation of 12 athletes, funded through private sponsorship, participating in four championship events and two U23 events.
