China is not the only one ‘militarising’ the South China Sea
Mark J. Valencia says it is unfair to blame Beijing for its defensive weapons systems in the Spratlys when the US and others are similarly provocative

First, it may well have not intended to “militarise” the features. But when Vietnam and the US took certain military action, Beijing may have felt a need to respond to perceived threats to its forces and assets. To China, Vietnam’s deployment of long-range mobile rocket launchers on five features within striking distance of China’s occupied features and continued US freedom of navigation operations close to them constitute threats.
Moreover, China apparently does not consider defensive installations “militarisation”. Indeed, China has repeatedly said that the artificial islands it has constructed would be used for military defence.
