Question

why has the international trade of India become easy

Answer 1

  International trade for India has become easier in the past few decades due to new technologies being introduced rapidly to the country. Most of the technologies in question are related to transport. With the advancement of transport technology, more goods can be exported and imported in and out of the country much faster.
 
  This advancement also means that these transport vehicles like cargo-planes and container ships can carry more goods which means that more inventory can be transferred each trip compared to the past. with globalisation, India has also been able to come into contact with countries that they weren't in with in before, thus there are more countries to trade with. 

Answer 2

The government economic reforms and liberalization policies have made it easy for international trade rather easy than ever before. The Foreign Direct Investment are allowed in many industries. Businesses (Small or Big) find it easy (more because of the strength of their currency over Indian Rupee) to experiment trading with Indian market which is safe as compared to other Asian Markets coupled with cost effective human resources. The economic ties with a number of dominant world powers have placed India as one of the primary Investment and Trading hub.
