This chapter addresses Macau’s place in China’s war with Japan from the early 1930s to 1941. Macau featured in Chinese resistance efforts from the start, but its relevance became more pronounced after 1937, especially after Guangdong province was engulfed in the conflict. The chapter argues that, due to its neutrality, Macau became an important meeting place for competing Chinese actors. Both those engaged in Chinese resistance – Nationalists, communists and others – and collaborators with Japan (before and after the consolidation of Wang Jingwei’s Reorganised National Government) used the enclave to circulate materials and propaganda, to mobilise others for their cause and to reach out to opponents.
