The proposed new city was presented to potential investors at the three-day conference, which began yesterday in the Red Sea resort of Sharm el-Sheikh.
Unveiling an initial plan in front of global leaders and diplomats attending the conference, Housing Minister Mustafa Kamel Madbuli said yesterday the new city will be built between Cairo and the canal city of Suez.
He said the proposed 700 square kilometre city will house up to five million people in 25 residential districts.
Cairo's population is expected to grow to 40 million by 2050 from the current 18 million, according to the website of the city.
Parliament, presidential palaces, government ministries and foreign embassies would move to the new metropolis from out of Cairo, the minister said, adding these projects would be executed over the next five to seven years at a cost of USD 45 billion.
An overall cost for the new city was not revealed, nor were details on how it would all be funded.
It will also have "an international airport, a theme park four times bigger than Disneyland in California, 90 square kilometres of solar farms, and an electric train" to link the new city with Cairo, he added.
"The master plan is to create a global city with smart infrastructure for Egypt's future, which will provide a multitude of economic opportunities and offer a distinct quality of life," an online plan of the city said.
President Abdel Fattah al-Sisi hopes investors meeting in Sharm el-Sheikh will help kick-start Egypt's troubled economy.
