The key word being, a weapon, I seen countless Indian papers and media saying a Chinese rail is in fact a plot and sinister in nature.
The rail have other purpose, and mostly it's not intended to harm anyone, but a weapon defensive or not can only destroy.
As I said I have no problem with sharing the news, but why say with an eye on China, why not just say you moved those there. It even says it's there to deter Chinese jets in this article's first paragraph.
We never say any weapon is intended for anybody, even the US don't say the pivot is about China, but clearly it is.
