This paper is based on English-language sources only. It uses official
US sources and some official Chinese sources, academic publications, and a
few news articles about recent relevant events. The difficulties encountered
in accessing Chinese sources (other than the official ones written in
English) and the secrecy cultivated by the Chinese government limit
understanding of China’s real strategy. Thus we acknowledge that
assumptions here may be subject to bias, due to the majority of sources
being American.
