India's M C Merykom asserted her supremacy for the second consecutive year by clinching the gold in the 46 kg class in the women's third World Boxing Championships at Podolsk, near Moscow in Russia.
Merykom showed her class as she claimed the back-to-back title with a huge 28-13 win against Jong Ok of North Korea in the final.
The Manipuri had won her second Asian title at Taiwan last month.
The diminutive boxer also has an envious record of reaching the final of the 48 kg in the inaugural edition in Turkey while winning the title in the previous edition in Pennsylvania.
She also won the gold and the best boxer award in the Tonsberg World Boxing tournament in Norway in 2004, besides various other international titles to her credit.
Indian pugilists put up an impressive show at the top level tournament by winning a gold and four bronze medals among 152 boxers from 28 countries vying for the top honours.
