This conclusion presents some closing thoughts on key concepts discussed in the preceding chapters of this book. The book examines China, and particularly its rise, through the lens of its interactions with its immediate, and in some cases not so obviously immediate, neighbors. China's engagement with its neighbors in diplomatic, social, cultural and, critically, economic terms has strengthened significantly over recent decades. Indonesia's official position is that it does not have a maritime boundary with China in the South China Sea. The People's Republic of China (PRC) and Malaysia have conflicting sovereignty over small South China Sea islands as well as overlapping maritime claims. America's insertion between China and its neighbors, partly in response to lobbying by Vietnam and others, angered Beijing, not least because it has long sought to exclude outsiders. In sum, Chinas expansive borders to the north are relatively quiet.
