Walkden, who lost against Zheng in the semi-finals at Rio 2016, defeated her rival 3-1 at the Sarhadchi Olympic Sports Complex.

Victory for the Rio 2016 bronze medallist ensured Britain’s third title of the two-day event following Charlie Maddock’s triumph in the women’s under 49kg and Jade Jones’ success in the women’s under 57kg earlier today.

After a scoreless first round, Walkden unleashed a rapid axe kick to Zheng’s face to take a 3-0 lead in the second.

The Chinese athlete managed to claw back one point in the third, but it was not enough to deny her opponent the win.

In the bronze match, the United States’ Jackie Galloway beat Mexico’s Briseida Acosta 1-0.

Walkden’s compatriot Jones showed why she is the Olympic champion in the women’s under 57kg category, beating Egypt’s Hedaya Malak 7-0 in the final.

It followed an emphatic 12-0 semi-final victory over South Korea’s Lee Ah-Reum, who went onto beat Jones’ team-mate Rachelle Booth 4-2 in the bronze medal match.

Arguably the most entertaining final of the day came in the men’s under 68kg category as South Korea’s Lee Dae-hoon claimed a dramatic 5-3 win over Belgium’s Jaouad Achab.

Achab struck first in the opening round with a twist kick to Lee’s body, but the Korean managed to level the scores from close range going into the second.

Lee scored to the body to make it 2-1 at the end of round two before Achab restored parity in the third with a back kick that drove his opponent out of the area.

With the clock counting down, Achab scored with a punch for a 3-2 lead only for Lee to return with a kick to the body that levelled the scores once more.  

In the last 10 seconds, a flurry of techniques that were too fast to call saw the scoreboard go to 4-3 and then 5-3 to Lee to settle an epic encounter.

The bronze medal match was an all-Russian clash between Konstantin Minin and Alexey Denisenko with the former winning by virtue of a golden point.

In the men’s over 80kg category final, Iran’s Sajjad Mardani defeated Russia’s Vladislav Larin 4-3 to take top honours.

The bronze medal went the way of Larin’s compatriot Roman Kuznetsov, who defeated Rio 2016 silver medallist Abdoul Issoufou of Niger 2-1.

Finishing second to Britain in the overall medal standings were South Korea, thanks to their two gold medals.

The WTF is set to hold its Gala Awards in Baku tomorrow, with the World Taekwondo Team Championships scheduled for Monday (December 12) and Tuesday (December 13).
