Kerry arrived in Egypt on his first visit to the Arab world since taking office for talks with the leaders of a country mired in political and economic crisis two years after the overthrow of autocrat Hosni Mubarak.With Egypt’s pound and foreign currency reserves sliding, the official said that if Cairo could agree on a $4.8 billion loan from the IMF, this would bring in other funds from the United States, European Union and Arab countries.However, the official said the United States believed Egypt needed to increase tax revenues and reduce energy subsidies - measures likely to prove highly unpopular."His basic message is it’s very important to the new Egypt for there to be a firm economic foundation,” the official told reporters as Kerry flew to Cairo."In order for there to be agreement on doing the kinds of economic reforms that would be required under an IMF deal there has to be a basic political ... agreement among all of the various players in Egypt,” the official said on condition of anonymity.Egypt said on Thursday it would invite a team from the International Monetary Fund to reopen talks on the loan and the investment minister expressed hope that a deal could be done by the end of April.Agencies
