Cambodia's financial system has undergone a significant transformation: from fragmented payments and limited access to an increasingly interoperable digital ecosystem built around national infrastructure. The opening remarks place that journey in the wider challenge facing emerging markets: how to modernise financial systems while preserving trust, monetary sovereignty and the ability to respond to domestic priorities. Cambodia's experience is presented not as a model to replicate, but as a record to examine - including the choices, trade-offs and lessons behind building national payment rails and connecting them beyond its borders. The remarks invite regulators, financial institutions and innovators to use the Summit to test what emerging markets must control themselves, what they can build or govern collectively, and where greater cooperation can create shared economic value.

The first choices made in a national payment system are difficult to reverse. Who owns the switch, who governs access, how fees are set and who pays for upgrades can determine the market that develops on top of it. Publicly funded rails can widen access but leave the state carrying long-term costs. Commercial models can create stronger incentives to invest while making access harder for smaller providers. Bakong offers one model: a national network connecting banks and e-wallets through shared infrastructure and interoperable QR payments. The panel compares the ownership, governance and funding choices available to emerging markets and asks which capabilities must remain under national control, which can be shared with industry, and what makes an open payment network financially sustainable.
