The opening day of the five-day-long annual meeting of the World Economic Forum (WEF), which began here on Wednesday, was marked by French President Jacques Chirac mooting four controversial proposals to raise adequate resources for global aid to poorer nations in Africa, Asia and Latin America.In a videolink appearance at a session just before the opening plenary, Chirac said the developed countries could consider raising levies on cross-border financial transactions, taxing fuel used in air transport and shipping, levying a one-dollar charge on every air ticket and imposing a levy on flows of foreign capital in and out of countries that maintain bank secrecy.
