PHNOM PENH, Cambodia (AP) — Diplomats say Southeast Asian leaders have decided to launch a human rights declaration despite last-minute calls for a postponement by critics, including Washington, who say the pact contains loopholes that can allow atrocities to continue.

According to diplomats, the 10 leaders of the Association of Southeast Asian Nations, an unwieldy bloc of liberal democracies and authoritarian states, will sign a document adopting the ASEAN Human Rights Declaration on Sunday in the Cambodian capital of Phnom Penh, where the heads of state are holding an annual summit.

The nonbinding declaration calls for an end to torture, arbitrary arrests and other rights violations that have been longtime concerns in the region.

Myanmar’s top diplomat, Wunna Maung Lwin, told The Associated Press that his country welcomes the declaration and will abide by it.
