As no country has infinite resources, grand strategy is effectively an exercise in prioritizing interests and attempting to advance those interests in efficient and effective ways. One of the key elements of grand strategy is "selective engagement". When the 21^(st) century began, Beijing became Washington's new target of "selective engagement" because China not only has emerged as a new Eurasian hegemon, but also has stepped into America's backyard. China is still miles away from matching America's international political reach. Nevertheless, Latin America has provided a significant opportunity for China to achieve its goals in its grand strategy. This article investigates how China aggressively has been asserting its economic clout to win diplomatic allies, ensure food and energy security, and accelerate financial internationalization. U.S.-China competition in Latin America is much more acute than the official declarations. This is the result of conflict of interests between Chinese and U.S. grand strategies toward Latin America.
