"There is a complementary economic relationship between China and Latin America and the Caribbean," said Wang Yi.
"We would like to deepen cooperation via the China-CELAC forum which will start this year," added Wang, who earlier visited Cuba, Venezuela and Argentina.
The Chinese president's upcoming July visit coincides with the sixth BRICS summit of developing nations, which will bring together the emerging economic powers of Brazil, China, India, Russia and South Africa.
And he will be in town during a meeting of representatives of the 33-strong CELAC group of Latin American and Caribbean states.

Wang said China was particularly seeking to invest in infrastructure projects -- chiefly roads, railways and power generation -- and he touched on the proposed creation of a "high value fund to aid infrastructure construction in Latin America and the Caribbean."
Energy-hungry China also has plans to increase investments in major oil producer Venezuela, as well as in Brazil, where last October a multinational consortium with Chinese participation won rights to develop Brazil's biggest oilfield.
