How much and what type of aid, (money, special services, support,
etc.) has the nation of India comitted to the recent tsunami diaster,
particularly in the
state of Sri Lanka?

5 INS(Indian Naval Service) ships. With a few choppers on them.
About 100 tonnes of aid.
with the aid totalling 25million$(excluding transport/logistical
costs) said Ms.Kumaratunga. Most of this aid was despatch immediately
after the tsunami hit.

The government has not let out more info on this though.

for the Maldives as well, Indian Naval ships and choppers were sent.
dont know the quantum of aid, but afaik India has some treaty
obligations with Maldives and is close to the administration/peopl, so
I guess it should have been a substantiative sum.

To Indonesia, India has sent 2 relief ships with one being converted
to a mobile hospital.

Thats the data available, now.
