Nepal, she says, is now seen as “the little engine that could” Dramatic proof of that comes in plans by India’s biggest business group, Tata, for a $2.5 billion investment in Nepal in steel, gas, coal and power.
Is the sentence above correct?
If then what is the meaning of the sentence?

Apart from the place-name, I have deja vu:

(The sentence is still structurally faulty.)

What kind of correction do you suggest?

4

As a minimum, a full stop is needed:
Nepal, she says, is now seen as “the little engine that could”. Dramatic proof of that comes in plans by India’s biggest business group, Tata, for a $2.5 billion investment in Nepal in steel, gas, coal and power.

I would also prefer an expansion of the second sentence:
Nepal, she says, is now seen as “the little engine that could”. Dramatic proof of that comes via plans by India’s biggest business group, Tata, to invest $2.5 million in steel, gas, coal and power in Nepal.
