Any strategy needs strength to support it.
To put it simply, India has no strength to support its strategy. Economy, military, industry, life expectancy, literacy, HDI, urbanization... Where do you think India is stronger than China?
Pakistan, Bangladesh, Sri Lanka, Thailand, Malaysia, and even Philippines are China's weapons customers. China's influence in these areas should not be overlooked. You talk to me about China's strategy?
Talking about missile technology? China exported DF-3 ballistic missiles to Saudi in 1988. And DF-21 exports Saudi in 2006.
