The United States Navy has launched its [largest annual humanitarian mission in the Indo-Pacific with a renewed focus on Southeast Asia](https://www.scmp.com/week-asia/politics/article/3357424/us-navy-flexes-soft-power-renewed-pivot-southeast-asia-amid-regional-rivalry), the South China Morning Post reported, in what analysts described as an effort to rebuild confidence and project soft power in a region central to its rivalry with China. The mission is a deliberate display of presence in waters where Washington and Beijing compete for influence.

Inside China's military, the focus is internal. The People's Liberation Army's (PLA) top anti-corruption officer, Zhang Shengmin, concluded an unusual training program for senior officers in Beijing by [urging greater loyalty to the Communist Party and political rectification](https://www.scmp.com/news/china/military/article/3357426/top-pla-graft-buster-urges-more-loyalty-political-rectification-training-ends). The campaign points to continuing concern in the leadership about discipline within the officer corps.

Considered together, the two developments show a regional contest taking place in two areas. The United States is rebuilding relationships across Southeast Asia, while China manages internal pressures within the force intended to project its power abroad.

## What this means

The Indo-Pacific contest drives an arms race and shapes the security of the world's busiest shipping lanes. Internal loyalty campaigns within the PLA indicate how confident Beijing is about its own military, a factor that affects the likelihood of confrontation as much as weapons do.

## What to watch

- Southeast Asian governments' responses to the US naval mission
- Further PLA personnel changes or anti-corruption actions
- Maritime incidents in the South China Sea
