New York, Aug 5 - More than two months after the Tamil Tigers were decimated, Sri Lankan Tamils living abroad remain bitter about the support China and India extended to Colombo during the war.

The Tamil Diaspora is livid that Beijing provided tonnes of arms and ammunition to Sri Lankan security forces battling the Liberation Tigers of Tamil Eelam (LTTE).

The anger against India is rooted mainly in New Delhi's diplomatic backing to Colombo when it came under Western fire over human rights abuses.

On Monday, Sri Lankan Tamils staged a rally outside the Chinese mission to the UN to protest 'China's assistance to Sri Lanka towards ethnic cleansing and genocide of Tamils'.

Around 50 Tamil Americans from around the East Coast came out with placards that read: 'China, Stop helping Sri Lanka's Ethnic Cleansing of Tamils.'

The group chanted slogans like 'China don't fund Sri Lanka's war crimes.'

The campaigners claim that Colombo's attacks on Tamil areas were facilitated by Chinese weapons. Beijing supports abuses against the Tamils through economic and military assistance to Sri Lanka, they said.

The rally was organised by Tamils Against Genocide (TAG), a NGO based in Maryland that is protesting against alleged atrocities committed by Sri Lanka.

A spokesman for TAG expressed dismay at New Delhi's support for Sri Lanka's military campaign that ended in the killing of LTTE founder leader Velupillai Prabhakaran and his top lieutenants in May.
