There is a treaty against the militarisation of space, but it doesn't cover this. Ironically India was recently arguing for it to be strengthened. https://www.nti.org/gsn/article/india-urges-strengthening-ou...
It's like Facebook asking for legislation.
"Look what we'll have to (feel we'll have to) do in the current paradigm, unless..."
Now in 2019 with 2 front war with both Pakistan and china, where both party have actively militarized the border with them and playing the proxy war it was sure coming. China vetoing 2 times action against J-E-M terrorist group based in Pakistan that are active in insurgency in Jammu and Kashmir state of India. They are also actively claiming the state of Arunachal Pradesh as the territory like they did with Tibet
China has also amassed large number of military installation near the North-Eastern border of India and have actively tried en roaching into Indian territories, several kilometers sometimes into the past few year resulting in border skirmishes sometimes.
Last time India declined the UNSC seat and gave it to china & they are still regretting the the decision. They are hoping the next NPT for Space will have India's seat already reserved.
If other nations are going to play game of dual diplomacy it's leaves no option but to demonstrate show of force. India cannot afford to become Another Ukraine, Tibet or Taiwan becomes some other nation can abuse it's power.
