I became aware of
sanda as martial art in 1990, thanks to the effort that
PWKA made in getting to Italy Chinese masters from the mainland and visiting periodically the PRC. Nowadays this is fortunately a common practice, but back then a good part of what was pushed for kung fu was in fact karate mixed with some made-up, esoteric looking sequence of movement.

Today sanda is a well known discipline available in any good gym of chinese martial arts, with a reliable definition in
wikipedia.
Actually the
sanda tournament rules I placed on my website back in 1997 are a bit outdated. Sanda today is structured in 4 main levels: beginners, amateurs, semi-professional and professional.
In a beginners tournament the athlets fight with a moderate contact (no KO), with 2 rounds of 1 minute each and a 30 seconds break between them. The fight is seamless, meaning that the referee does not stop the match to assign points.
Amateurs fight with KO, with 2 rounds of 2 minutes each and a break of 1 minute. A third round is required if the score is even at the end of the second one.
Semi-professional athlets fight on the distance of 3 rounds of 2 minutes each, while a professional match spans over 5 rounds of 3 minutes each, with a break of 60 seconds.
The use of elbows and knees is now permitted, and only in the professional category. Another important difference is that semi-professionals and professionals wear only boxing gloves, mouthpiece and groincup (no headgear or chest protection), much like in the other kickboxing disciplines. In fact sanda athlets begun to partecipate to K1-like tournments with interesting results.
But then I would argue that sanda without takedowns is just kickboxing, because the strategy for close-quarter, which I believe to be the most distinctive element of sanda, is just the same.
