China has the expertise and is willing to participate in Argentina's efforts to revitalize its transportation infrastructure and develop nuclear energy, Premier Li Keqiang said on Thursday in Beijing.

China has the technology, high-quality equipment and competitive prices, Li said, adding that the two countries are natural partners for cooperation because both are developing and their markets are emerging.
