India said here on Wednesday that food security is a no-bargain issue. Anand Sharma, Indian Minister of Commerce and Industry, told the WTO meeting held here from Tuesday to Friday that food security is essential for 4 billion people in the world. "For India, food is non-negotiable." Furthermore, the minister said the continuing stalemate of Doha Round has led to frustration and cynicism when this was the only round devoted to the development agenda. "Historical imbalances in trade must be corrected," he added. The WTO ministers' meeting, with the participation of trade chiefs of the organization's 159 members and other 10,000 diplomats from more than 160 countries and regions, is struggling to revive the long-stalled Doha Round by reaching a possible trade deal.
