Malaysia is visa free for Indians as of now.

It is unfortunate Govt of India doesn't allow flying domestic destinations via international hub. So we've to book two separate tickets, clear immigration etc. Many other countries do not have such restrictions. In Taiwan you can fly from Kaohsiung to Taipei via Hong Kong or Manila or some other international destination.

More such examples will be available if you dig deeper.
