"We are here to display the railways and heavy equipment we have. We would like to see Africa having these high tech railways connected to each other," Jia said.

The activities of this company include manufacturing sophisticated turbine boring machinery as well as installing and maintaining railways. China Railway Construction Corporation managed to sign deals totalling 177 billion U.S dollars with African countries namely Zimbabwe, Zambia, Namibia and Nigeria.

The exhibition also went a long way in affording African companies to showcase their products to the outside world.

Gavin Boy, Director at McKinley Chocolates, which is a South African company, said he was happy that next month they will start receiving chocolates from a company in Kazastan for resale in South Africa. He also praised the Chinese market as a potential place for his company's chocolates.

Boy said, "The Chinese market is hungry and aggressive. We are hoping to sell our products to China soon."

The organizers of SAITEX Exhibition Management Services described the 2015 exhibition as a success. The 1,000 companies that attended the exhibition came from 66 countries, a remarkable increase from the 55 countries that were represented last year.

John Thomson, Managing Director of Exhibition Management Services, said, "Over 12, 000 visitors came to the exhibition in the first two days. Some have agreed on partnerships and business deals with South African companies and this will assist in employment creation and economic growth of the country," he said.

Thompson said he expected deals worth billions of dollars to come out of the exhibition. "Many companies signed deals during the exhibition while others will do so in future. We are proud as organizers to provide such a crucial platform for business development in different countries," Thomas said.
