After the launch of the second five-year plan, what did the government do to protect domestic industries?

The government imposed substantial tariffs on imports.

The Congress party at its session held at Avadi near the then Madras city passed an important resolution. It declared that the ‘socialist pattern of society’ was its goal. This was reflected in the Second Plan. The government imposed substantial tariffs on imports in order to protect domestic industries. Such a protected environment helped both public and private sector industries to grow.
