"President Barack Obama should start candid conversations with China's leader-in-waiting about the pressing issues that define U.S.-China relations -- the most important and complex bilateral relationship in the world," writes Fei-Ling Wang, professor in the Sam Nunn School of International Affairs. Wang authored this CNN Opinion article in anticipation of Xi Jinping's visit to Washington this week. He writes later, "Since no one knows what Xi really has in mind for China and its future, a productive meeting is one in which the two can start building trust and a good working relationship."
