Ms Karthikeyan had climbed another ''above 6,000 m'' peak, Mt Stok Kangri, in August 2017, becoming the youngest in the world to do so, a defence spokesperson said on Thursday.
Her mission is to conquer the highest peaks in every continent and ski to both Poles, he said.
She has already scaled the highest peaks in Africa, Europe and Australia and is preparing to take on Mt Aconcagua (6962 m), the highest peak of South America, he added.
