At this point, some Indian soldiers tried to come to the aid of their Chinese counterparts but Sitharaman asked them to let the PLA men find the meaning on their own.
In another video that was tweeted from the official handle of Sitharaman's office, the defence minister is seen interacting with a Chinese officer, who then introduced her to his colleagues and describes their job roles at the border.
But it was soft diplomacy at its best when defence minister Nirmala Sitharaman greeted Chinese military officials with an Indian customary "namaste" at the Nathu La border during her official visit to the place.
Actually, most Chinese soldiers don't know English.
Sitharaman then asks the Chinese equivalent of "Namastey". In the video, the minister is seen explaining the meaning of "Namaste" to PLA soldiers stations along the border.

The defense minister's visit to the border area comes more than a month since Indian and Chinese troops disengaged after almost a 70-day standoff at Dokalam.
The minister earlier took to Twitter to share a post showing her waving at Chinese troops who were taking pictures of her from across the border.
He said uncertainly, "Nice to meet you?"
The Doklam standoff between India and China started after Indian Army stopped the construction of a road in the area which is disputed between China and Bhutan. The Minister reiterated the Government's resolve to give further impetus to development in the border areas.
She was accompanied by Vice Chief of the Army Staff Lt Gen Sarath Chand and GOC-in-Chief Eastern Command Lt Gen Abhay Krishna.
