Some left-leaning parties staged separate demonstrations against discriminations to poor nations at the meeting of World Trade Organisation (WTO) ministers in the Mexican resort.

"We want punishment to those responsible for the death of farmer Lee Kyang Hae," Shireen Akhter, president of Karmojibi Nari, told a rally at Shahbagh.

"We will not allow the Cancun meet to succeed if it does not take the demands of poor nations into consideration," she said.

Hae stabbed himself in the chest during the demonstrations in Cancun on Wednesday and later died in hospital. One of his friends said his suicide was an "act of sacrifice" to show his disgust at the WTO and its policies.

Four left-leaning parties from a rally at Muktangan urged Commerce Minister Amir Khosru Mahmud Chowdhury not to sign any agreement at the Cancun meet that goes against the interest of the least developed countries (LDCs) including Bangladesh.

They vowed to build up a tougher movement against the government if it inked any agreement at Cancun that would hamper Bangladesh's interest.

The Jatiya Gano Front, Biplobi Oikya Front (BOF), Ganotantrik Majdur Party (GMP) and Ganosanghati Andolon orgaised the rally.

Nazrul Islam, a coordinator of the left-leaning parties, said the developed countries were pressing the poor countries to withdraw farm subsidy, but the developed countries including the United States were heavily subsidising their agriculture sector.

Terming the WTO 'an anti-poor organisation', he said it by no means served the interest of poor nations including Bangladesh.

Moshrefa Mishu, convener of the BOF, said duty- and quota-free access would not serve the interest of the LDCs, rather the rich countries would control their markets.

Pegging the WTO as 'an organisation of rich countries', Abdus Salam, politburo member of the GMP, said it always planned plunder of poor nations' wealth.

"The government is interested in going by the suggestions of the US rather than considering the interest of the people," he added.

The rally was presided over by Zonaed Saki, convenor of the four left-leaning parties.

The demonstrators later brought out a procession that paraded through Gulistan and Paltan area.
