Opposing Sri Lanka hosting the Commonwealth Heads of Government Meeting (CHOGM), he urged the trading community to close down shops unmindful of the losses in the interest of Tamils.
The closure call was aimed at stressing for expulsion of Sri Lanka from the Commonwealth league of nations and also "condemn the UPA for its betrayal by assisting Sri Lanka in the genocide (of Tamils)," by providing arms and funds, he said in a statement.
Vaiko-led MDMK, 'May 17 Movement', Thanthai Periyar Dravida Kazhagam and Manithaneya Makkal Katchi had also decided to resort to rail blockades.
Meanwhile, protests continued in different parts of the state pressing for India's boycott of next week's Commonwealth Heads of Government Meeting (CHOGM) in Sri Lanka.
More than 100 VCK members were arrested when they staged staged rail-blockade at Chennai and Nagapattinam, police said.
The Tamil Nadu Assembly has adopted a unanimous resolution recently opposing India's participation in the CHOGM.
