They all "feel proud to be part of the national project and seek to implement it in the best shape," the Egyptian engineer said, giving a cheerful enthusiastic smile.

Still working on the ground tests, Girgis said "the construction of the tallest tower will be carried out" in a matter of four to six months.

It's a race against time, the Egyptian engineer said, expecting the tallest tower to be completed in no more than two years.

"Their spirit here is more about feeling proud to share with the Egyptian people in accomplishing their national dream," Girgis said.

The Chinese contribution in a large national project in Egypt has reflected the Asian power's commitment toward Egypt and signalled the historical ties between the two countries, said Diaa Helmy, secretary general of the Cairo-based Egyptian-Chinese Commerce Chamber.

"The CBD is one of these projects that China constructs in Egypt not just to gain economic benefits, but to indicate its support for the North African country," Helmy told Xinhua.

"China seriously aids Egypt and we also have the same sincere feelings toward our friends, which were manifested in supporting the Belt and Road Initiative that will bring fruits to the entire region," Helmy said.

The initiative, proposed by China in 2013, aims to build a trade and infrastructure network connecting Asia with Europe and Africa on and beyond the ancient Silk Road trade routes.

Helmy believed the new capital has good potentials for other leading Chinese companies in building bridges and tunnels that will be part of the new capital.

He also expected fruitful mutual cooperation in the field of smart city, digital technology and renewable energy needed in the new capital.

The constant cooperation between the two countries in the national projects in Egypt, as well as the investment along the Belt and Road, will pave the road for a bright future, Helmy said.
