Developing new crop varieties is essential to improving yields – and, in turn, a country's food and economic security. In China's southernmost province of Hainan, year-round warm weather creates ideal conditions for breeding experiments. Alongside Chinese scientists, many international researchers, particularly from Africa, study and train there. CGTN speaks with scientists in Hainan and follows one researcher back to Ghana to see how this partnership is training talent and strengthening global food security.
