Romania also won a first world title of the competition, while there was a gold medal for Uzbekistan too.

It was a perfect start to the night's finals for Russia as Anastasia Valova found a way through to force a submission from Romania's Daniela Poroineanu in the women's 56-kilogram division.

This was despite Poroineanu coming close to securing victory herself earlier in the contest.

The victory meant Russia won each of the three lightest weight categories, but the same was not meant to be in the men's contests.

Uzbekistan's Davlatjon Khamroev put an end to that possibility, defeating Aleksandr Matais via a decision in a tight 62kg final.

The combat sambo 52kg final was exciting, but ended prematurely when Russia's Vladimir Lamanov made Kazakhstan's Yerkebulan Kuangaliyev submit with a minute still to go.

Both had led the bout at one point, with Kuangaliyev pulling off a monkey flip to take his opponent down, only to fall behind after Lamanov landed a headbutt - taking the Kazakhstani off his feet to put Lamanov 6-2 up. 

Kuangaliyev was undone by an armbar just a minute later, giving Lamanov the victory.

Romania's first gold medal of the 2020 World Championships came thanks to a kimura submission Volha Maleika put on Belarus' Nastassia Skvartsova. 

Skvartsova had already fallen a point behind in the women's 68kg final due to a passivity penalty.

A third Russian gold medal of the day was won by Samvel Kazarian in the men's 82kg.

His opponent, Dmitro Stetsenko of Ukraine, took an early lead thanks to an outside leg hook for a single point.

But Kazarian responded well with a massive take down for four points and from there held onto his lead to win the world title.

Another Russian gold medal was won minutes later in the most dominant final performance of the tournament, courtesy of Sheih-Mansur Habibulaev.

Both Habibulaev and Emil Nezirov of Bulgaria started the 68kg combat sambo final in a fast fashion, with a feeling-out process completely absent.

Habibulaev scored four points within the first 30 seconds and added another four with less than half the time expired to confirm his victory.

Russia won the event's final three titles, starting with Olga Artoshina in the women's over-80kg.

She beat Ukraine's Vasylyna-Iryna Kyrychenko in less than 90 seconds.

Artem Osipenko, despite having to have his wrist taped up early in the bout, looked incredibly comfortable in his men's over-100kg final.

His opponent, Dzmitry Khakhlou of Belarus, was completely nullified throughout the five minutes of play.

The final bout of the World Sambo Championships saw Sultan Aliev defeat Louis Laurent of France - the more experienced individual bettering a relative newcomer in the combat sambo 90kg final.

Despite his loss, Laurent's silver medal was France's best performance at the 2020 World Championships.

Other notable performances included Serbia's Vladimir Gajic winning the host nation its second bronze medal of the Championships in the men's over-100kg.

Russia ended the World Championships with 25 medals - 17 of them gold.

Belarus came second in the medals table, with Ukraine third.

Nineteen nations won medals in all.

The next International Sambo Federation's next World Championships are currently scheduled to take place in Moscow in 2021.
