To term the market-oriented changes as reform is a 18. The development strategy 19 under Structural Adjustment and dictated by the World Bank, IMF and WTO is a strategy for the 20 development of capitalism under which the working people, who are the main productive force, are made 21, kept unemployed, thrown out of jobs, and so on. It has no social relevance. In the phase of globalization, no country can develop in 22 and entry of the foreign capital can not be 23 altogether. Integration with world economy has to ensure the free and speedy 24 of the national economy. Foreign capital has to be allowed in the areas where we really need huge investment, which our resources cannot meet, and where we need technology, not available in the country.
