Original sentence: India is generally considered not to be a superpower, but a potential superpower.Many argue for example, that due to the European Union having a population larger than the United States, the largest economy in the world, low inflation rates, the unpopularity and perceived failure of US foreign policy in recent years, and certain EU member states' high quality of life (especially when measured in terms such as hours worked per week, health care, social services), that the EU is a qualified superpower.Many prominent economists label both entities superpowers.Similar points can be made for China, however some believe these facts are not qualifying factors.The definition of a superpower is not clear, therefore there tends to be disagreement on whether certain entities qualify for superpower status.There are some that view India's qualification for superpower status is far from certain, and that India may never emerge as a superpower.While it is universally agree that the United States is a superpower, the same can not be said for the European Union and China
Edited sentence: Due to their large markets, growing military strength, economic potential and influence in international affairs; China, the European Union and India are among the countries (or political entities) most cited as having the potential of achieving superpower status in the 21st century.While many view entities such as the European Union as already qualified for superpower status, many also believe this is not the case and furthermore, that it is far from certain that some or all of these countries will ever emerge as superpowers
