There are not many nations who do good in more than 1 combat sports, simply because fighting is not very developed and kind of decreased. Talking about the Big 3, not mentioning karate and jiu-jitsu, and kempo and one more discipline I forgot the name (in wushu so so now), where we are winning a lot of medals. In Romania we have 5-6 kickboxing promotions with good TV contracts. 4 world champions in pro-boxing after 1990, when pro-boxing appeared, I am fine with it. Netherlands might have 0 in first 3 belts, and don"t come here also with WBA Regular which is not Super. IBF, WBA and WBC. That"s all... Plus Romania has in amateur boxing 115 medals, only Russia and Germany have won more in European Championships! England has less than 60, Great Britain included. Netherlands has 5 times less than Romania. Even in women we are 5th overall.
Now I have a boxing background, ok? And I know everything. Then this Oriental body AIBA has brought corruption to amateur boxing, then most of our potential boxers migrated to kickboxing. It"s an inside job the destruction of boxing, this is why boxing is decreasing big. Amateur boxing today is not taken seriously anymore, and pro-boxing in the US is at the worst state ever. Who has the TV wins it. Kickboxing had the perfect recipe in Romania. The same professional boxing in Great Britain. Eduard Irimia migrated from pro-boxing (held some events with important titles) to kickboxing in early 2000. Every respectable fitness gym in Romania includes now kickboxing, sometimes BJJ/MMA but not boxing. And karate had overtaken here boxing decades 2 decades ago.
Muay Thai for me is not even a real fighting sport. It"s Thai (kick)boxing. It is not taught anymore in my country. For example we have many karatekas. For example Romania youth and juniors ranks number 1 in karate as medals in 2019, with over 200 trophies won at the European Championships. Over 300 medals in Euro and World champs.
So if you think we struggle, it is not true. Where we have athletes, we have results. The number of athletes in boxing has simply decreased big. About 25 times.
Plus who are the current Dutch Muay Thai fighters? Waiting names.
