Re: India has rights of an elder brother, says Lanka.
‘It is high time that Sri Lanka understood that India is the big power in the region and ought to refrain from going to Pakistan or China for weapons, as we are prepared to accommodate them within the framework of our foreign policy,’ Narayanan told reporters after a 45-minute meeting with Tamil Nadu Chief Minister M. Karunanidhi here.
It was actually your National Security Advisor M.K. Narayanan…
Jist is that India doesnt appreciate Sri Lanka buying military equipment from Pakistan or China, because India is a local super power and thus all such needs should be met throught India… 
No one agrees with the Sri Lankan govt… But India needs to stop playing big brother… No one in the region will appreciate your meddling no mater what moral high ground you try to occupy.
