Opinion | In a post-James-Mattis South China Sea, can the next US defence chief do what needs to be done to prevent war?
- Mark J. Valencia says the new US defence secretary will have to understand, as James Mattis did, the balance required for the US to stay in the Indo-Pacific as a leading strategic power but also prevent conflict with China

The US-China tensions in the South China Sea spring from a deeper contest over the future of the Asian regional order and the two countries’ roles in it. To put it simply, the US wants to remain the leading strategic power in Asia, and China wants to replace it.
President Xi Jinping has declared: “No one is in a position to dictate to the Chinese people what should or should not be done.” With its burgeoning wealth and power, China is unlikely to be intimidated and begin to act more cautiously in the region.
Indeed, it is more likely to meet threats and provocative actions with its own. Nationalists in the government, in the Chinese navy, and among netizens might push for responses to provocations. More military-to-military incidents are likely, and past international episodes might seem minor by comparison.
