However, she said United Nations rules do not allow Hindi to be made an official language at the world body. "Hindi is an official language in Fiji, so do not say that it is an official language only in India", Swaraj shot back at Tharoor.
Therefore, according to the UN rules, support of two-third member-countries (129 nations) is required out of the total 193 member-nations, Ms Swaraj said in the Lok Sabha during Question Hour.
"It is not hard to get the support of two-third member nations".
After Swaraj asserted that the government was willing to go to any lengths to get Hindi the status of official language in the UN, Tharoor questioned the government's need to push a language that was spoken by the people of only one country.
"For us to be spending government resources, for seeking to promote Hindi in this objective raises an important question as to why do we need to make it an official language?" asks Tharoor.
"Not just Rs. 40 crore, the government is ready to spend Rs. 400 crore on it", added Swaraj, who blamed the voting system at the United Nations. Arabic does not have more speakers than Hindi, but Arabic is spoken by 22 countries, whereas Hindi is only used as an official language by one country - us", he said.
Replying to a written question in the Rajya Sabha on whether construction of dams by China on the tributaries of the Brahmaputra has contaminated its waters, the minister said the government has noted the Chinese foreign ministry's statement denying such a link and that it was caused by an quake in the region and was not a manmade incident.
Also, spending taxpayers' money on something so trivial is not acceptable. He stated that there is nothing wrong with taking pride in the Hind language, but it would be wrong to impose on Minister who don't speak Hindi.
He pointed out that Hindi was India's official, not national, language. Seeking to promote Hindi raises an important question.
"The government has to defend its position".
The statement did not go well with several members of the treasury benches who raised the pitch in protest.
It said the Joint Commission meeting and other engagements of Sushma Swaraj would enable the two countries to chart out the course of partnership during the year 2018.
As Swaraj and Tharoor traded barbs, once again it is clear that in a country where every state has its own languages and dialects, promoting only Hindi at any worldwide podium might prove to be a "costly" affair for the country. If they speak in their own language, we speak in Hindi.
