Vietnam's leader, To Lam, warned at the Shangri-La Dialogue, the region's main annual security summit held in Singapore, of [three foundational crises](https://www.scmp.com/week-asia/people/article/3355374/shangri-la-dialogue-vietnams-lam-warns-3-crises-converging-asia-pacific-security?utm_source=rss_feed) converging at once, those of international order, development models and strategic trust, the South China Morning Post reported. He delivered the assessment in the keynote address.

The warning landed against fresh maritime friction. China called talks between Japan and the Philippines over a sea boundary [illegal](https://www.thehindu.com/news/international/china-calls-japan-philippines-sea-border-talks-illegal/article71038756.ece), The Hindu reported, amid continuing disputes in the East China Sea where coast guard ships from rival claimants stage frequent standoffs.

The Asia-Pacific region carries the densest concentration of global shipping, manufacturing and semiconductor supply. A breakdown in strategic trust there would disrupt the supply chains on which the world economy depends, which is why these diplomatic signals carry weight far beyond the immediate parties.
