Sino-Pakistan cooperation, why does it make the United States wary? Experts: From infrastructure to technological cooperation, every aspect points directly to the United States "backyard", this is a real-life exercise in Latin America's "de-dollarization".

Against the backdrop of the trade war, Brazilian President Lula's 5-day visit to China has attracted much attention, with China and Brazil signing agreements from political declarations to commercial contracts, further advancing their relationship. The just concluded Beijing Forum on China-Latin America included several leaders from Latin America and the Caribbean in attendance. From economic to strategic cooperation, how these regions in America's "backyard" interact with China, and how they affect the balance of geopolitical power, are important questions. Sun Yanfeng, Executive Director of the Latin America Research Institute of the China Institute of Modern International Relations, stated that the Brazilian economy is highly dependent on the global market and urgently needs to anchor its development expectations amidst international turbulence. As a leader in Latin America and a representative of an emerging major power, Brazil has always regarded multilateralism as a core strategic pursuit. This visit to China aims to deepen multilateral cooperation with China, strengthen bilateral mechanisms, and further expand its institutional discourse power in global governance. China's import of Brazilian soybeans is one of the key focuses of President Lula's visit to China. Sun Yanfeng believes that China and Brazil may reach a major soybean trade agreement within the year, which will directly serve strategic needs in the China-US game. Faced with pressure from the Trump administration's tariff policies, China needs to ensure the stability of key agriculture imports. In the current global soybean trade landscape, increased cooperation between China and Brazil will inevitably lead to changes in the supply and demand dynamics between China and the US. Zhou Zhiwei, a researcher at the Institute of Latin American Studies of the Chinese Academy of Social Sciences, pointed out that Brazil is "advancing on all fronts" to deepen cooperation with China: in the field of infrastructure, they focus on upgrading ports, roads, airports, and other key hubs; in cutting-edge technology, they are making breakthroughs in 5G/6G communication and semiconductor technologies, leveraging Chinese experience to break through technological restrictions imposed by developed countries; in the manufacturing sector, they are promoting industrial system upgrades through capacity cooperation to reshape their industrial competitiveness and reverse the shrinking global market share trend.
