I will be blunt. There is no way for India to grow its manufacturing exports until the world solves its China problem.

After the collapse of real estate, China is redirecting all its energy towards exports. 

The way credit is being driven, coupled with collapse in domestic  demand, means Chinese products will continue to be cheap. Currency depreciation is another tool China has.

Given the structural advantages and established manufacturing ecosystem, it is impossible to beat China.

So unless the US puts 100% tariffs on Chinese goods (including reexports from Mexico, Vietnam), China will dominate the exports market.

It's just not India, even traditionally strong export countries like Germany, S. Korea and Japan are struggling against Chinese juggernaut. 

Other than collapse and revolution in China, I don't think for the next 5 years it is easy for India to grow manufacturing exports easily.

In fact, it is very important that India protects its domestic demand. Look at the steel sector, where every manufacturer is calling out the cheap Chinese that is being dumped. A lot of planned capex is being scaled down.

The only thing Modi government can realistically do is save Indian domestic market. Everything else is beyond Modi.

(Unless Modi can transfer 5-10% of GDP as PLI + Industrial subsidy, which would also mean stopping all farmers, ladli behan, and other common people subsidies)
