The latest report from C4DS says that Chinese companies have pledged billions of dollars to develop maritime ports and related projects across the Indo-Pacific Region since China announced its strategy to increase global trade connectivity through the Belt and Road Initiative (BRI). Some states question whether China’s infrastructure investments are driven by strategic interests, with use of such bases by naval as well as commercial vessels. The report evaluates China’s maritime infrastructure investment goals in the Indo-Pacific within the context of both policy from official documents and analyses from state- and Communist Party-affiliated publications. The report also analyses a sample of 15 China-funded port projects to assess the behaviour of the Chinese state and the Chinese companies involved using open-source data and, in some cases, on-the-ground investigation. The investments appear to generate political influence, stealthily expand China’s military presence, and create an advantageous strategic environment in the region.
