China's Tan Yujiao and Ye Jixiong celebrated gold on the fifth day of the World Para Powerlifting Championships in Mexico City.
Yujiao headed into the women's up to 67 kilogram competition as the defending champion and she retained her title in impressive style at the Juan de la Barrera Gymnasium.
A lift of 135kg in the second round was enough to secure the gold, with none of her rivals proving able to better the weight.
The Paralympic champion attempted to beak her world record of 138.5kg in the third and additional fourth round, but ultimately fell short of achieving the feat.
Nigeria's Olaitan Ibrahim settled for second after an opening lift of 110kg, while a 105kg effort was enough for Egypt's Gihan Abedlaziz to take the bronze.
Jixiong emerged as the winner of the men's up to 88kg event, with the Chinese star achieving a best lift of 226kg, having already achieved 215kg and 220kg.
The Championship debutant finished convincingly clear of Iran's Seyedhamed Solhipouravanji, who won silver with a lift of 210kg.
Brazil's Evanio Da Silva also marked his World Championship debut with a medal, as the Paralympic silver medallist achieved a total of 208kg to take bronze.
France's Souhad Ghazouani triumphed in the women's up to 73kg event with a successful lift of 145kg, before falling short of breaking her own world record of 150kg.
"I did not expect this result at all, I am happy to win another world title," she said.
"I wanted to break my world record but I could not.
"I'll try again at the 2018 European Open Championships in my home country."
The podium was completed by China's Han Miaoyu and Nigeria's Paralympic champion Ndidi Nwosu, who managed 121kg and 120kg respectively.
The Para Swimming World Championships, which is being held alongside the powerlifting event as part of a Para Sport Festival, also continued today.
Sarai Gascon emerged as the winner of the women's 100m butterfly S9 event, which proved the closest race of the day.
She finished in a time of 1min 9.52sec, edging China's 15-year-old swimmer Xu Jialing by just 0.09sec.
Nuria Marques Soto rounded off the podium, with the Spaniard achieving a time of 1:10.27.
China's Wenpan Huang won his third gold of the Championships, as he achieved a world record 38.81 seconds in the men's 50m freestyle S3 competition.
He was followed by Mexico's Diego Lopez and Italy's Vincenzo Boni, who managed 39.70 and 46.71 respectively.
Brazil's Daniel Dias concluded his participation in Mexico by earning his sixth gold, as he triumphed in the men's 200m freestyle S5 final.
Dias won the event in 2:37.67, with Theo Curin of France trailing 14.83 seconds behind to take the silver medal.
The podium was completed by China's Li Jungsheng, who finished in 3:05.74.
