The movie won't even make it to Nepal, thanks to their Indian TV channel ban, and tight communist information control.
The only way India can turn around its Nepal fuck-up is through hard power. You cannot beat commies with soft power, and you'll never be able to outspend the Chinese. Once you convince Kathmandu that India can do a lot more damage to Nepal than China can damage/help Nepal, they'll crawl back into our sphere of influence, or at least adopt some kind of neutrality/equidistance.
Nepal has India on 3 sides, highly accessible, and China on one, behind a wall of mountains. China cannot defend Nepal against India, unless it colonizes Nepal and puts 20 mechanized divisions along the Nepalese border with India.
