How does a government respond to a threat or coercion by a larger and better-resourced military? That is a question faced by countries across the Indo-Pacific when it comes to actions conducted by the People’s Republic of China (PRC).

This report focuses on how these two Indo-Pacific countries responded to actions conducted by the military apparatus of the PRC since 2022.

In the South China Sea, the Chinese leadership is intent on controlling all the rocks, reefs, and resources in the waters encompassed by what has become known as the ‘nine-dash’ or ‘U-shaped’ line. This line, which first appeared on an official map published by the Republic of China (ROC) in 1948, has no legal or historical basis. It is the product of misunderstandings and mistranslations by officials and private individuals in China during the 1930s. Unfortunately, this line is the basis for ongoing confrontations and escalating geopolitical tension between the People’s Republic of China (PRC), its Southeast Asian neighbours and other countries.
