PHNOM
PENH, March 26, 2026 — Cambodia has rejected calls by a Thai Senate
panel to revoke a long-standing border agreement, warning that such a
move would violate international law and undermine efforts to maintain
peace along the border.
In a
statement, the State Secretariat of Border Affairs said it “firmly
rejects and entirely dismisses” recommendations to cancel the 2000
Memorandum of Understanding (MOU 43), describing them as unfounded and
politically motivated.
The MOU,
signed by both countries and registered with the United Nations, serves
as a legal framework for resolving border issues through the Joint
Boundary Commission (JBC).
Cambodia
said Thailand cannot unilaterally revoke the agreement under
international law, citing the Vienna Convention on the Law of Treaties.
Officials
added that the JBC has made progress in demarcation work, including
identifying boundary pillars and conducting joint surveys.
Phnom
Penh reaffirmed its commitment to resolving disputes peacefully and
warned that revoking the agreement would hinder stability and
cooperation along the border.
