【摘要】：China and the US differ sharply in their models of international development assistance. Because the US strengthens development assistance as a strategic investment, it has a privileged position under current international rules. China has expanded in regional markets using more cooperation and is there recreating the rules in trade, investment and infrastructure. To deal with China's policy on international development,the Trump administration is promoting a geoeconomic game and trying to make its US model more attractive. This gives a glimpse into how the US has begun a systematic balancing. International development assistance has been a security tool,and now becomes the main battlefield of competition between the two countries.
