A parallelogram is a quadrilateral formed from two sets of parallel lines.

Also, developing countries and the least developed countries faced 48 per cent higher trade weighted average tariffs in the markets of the Quadrilateral Group of Industrialized Economies than in other countries of the Organization for Economic Cooperation and Development owing to the composition of their exports in relation to the tariff structure of developed countries.

We have not yet seen any renewed attempt to re establish the Quadrilateral Security Dialogue, comprising Japan, Australia, the US, and India, which conducted joint military exercises in 2007 and was seen by China as a hostile containment enterprise. But it is not hard to imagine that this is still very much on Abe s wish list.

That project involves, first, the Golden Quadrilateral, connecting the four major cities of Delhi in the north, Mumbai in the west, Chennai in the south, and Calcutta in the east secondly, the north south and east west corridors connecting Srinagar in the north to Kanyakumari in the south, and Silchar in the east to Porbandar in the west and, thirdly, port connectivity and other projects.

For instance, UNCTAD estimates have found that during the 2001 2002 period, 61 per cent of exports of least developed countries to the Quadrilateral Group of Industrialized Economies (Canada, the European Union (EU), Japan and the United States of America) faced most favoured nation tariffs owing to their exclusion from the Generalized System of Preferences or other preferential schemes or their inability to qualify for the preferential treatment and the complexity of utilizing the schemes.
