Yayi met Hu on Tuesday and the Benin president was expected to hold further talks with Chinese Commerce Minister Chen Deming as well as business leaders on the sidelines of a summer session of the World Economic Forum.
The forum is being held in the Chinese port city of Dalian.
“The two heads of state spoke on bilateral cooperation, particularly commercial, agricultural and construction issues,” said Vincent Dassi, an adviser to Yayi, who is to remain in China until September 20.
As is the case in a growing number of African nations, China has financed a number of important infrastructure projects in Benin, a former French colony with a population of some nine million people.
Such projects include roads and health infrastructure, as well as the country’s largest stadium and a new foreign ministry building.
Yayi, an economist, won re-election in March.
