The Cambodian Ministry of Foreign Affairs and International Cooperation has briefed foreign diplomats on the latest developments concerning the Cambodia-Thailand border situation, expressing concerns over unilateral claims and illegal activities by Thailand. Phnom Penh urged the swift resumption of joint border demarcation work to ease tensions. On the afternoon of July 3, 2026, Deputy Minister of Foreign Affairs and International Cooperation, H.E. Ms. Eat Sophea, presented the latest developments regarding the Cambodia-Thailand border situation to the heads and representatives of 42 diplomatic missions and international organizations in Phnom Penh. The briefing focused particularly on the strengthening of Thai forces' occupation in areas beyond the border line unilaterally claimed by Thailand. H.E. Mr. Eit Sothar, Permanent Secretary of State of the Secretariat of State for Border Affairs, also participated in the briefing, explaining the internationally recognized international border line as defined and demarcated by the Franco-Siamese Conventions of 1904 and 1907, and comparing it with the border line presented on maps unilaterally drawn by Thailand. H.E. Ms. Eat Sophea recalled the de-escalation measures agreed upon in the Joint Communiqué of the 3rd Special Meeting of the Cambodia-Thailand General Border Committee (GBC) dated December 27, 2025. She emphasized that one of the most crucial measures agreed upon to ease the tense situation, restore confidence, and achieve long-lasting peace between the two countries is the prompt resumption of the demarcation work by the Joint Commission on Demarcation of the Land Boundary (JBC), with immediate priority given to areas where citizens reside. The continuation of the JBC's work will allow tens of thousands of remaining citizens to return to their homes and resume their normal livelihoods, as agreed. However, since the new Thai government was established at the beginning of this year, there has been no indication that Thailand has implemented measures to fulfill its commitments under the comprehensive agreement, and illegal activities in the areas under its occupation have continued without interruption. She also highlighted the significant role of the ASEAN Observers Team (AOT) in supporting the implementation of the ceasefire agreement and expressed Cambodia's profound gratitude to Malaysia and the Philippines for leading the AOT as the former and current ASEAN Chairs, respectively. H.E. Ms. Eat Sophea reaffirmed Cambodia's unwavering commitment to resolving border and maritime border issues with Thailand peacefully, in accordance with international law and existing bilateral agreements. She expressed confidence that continued adherence to international law principles and constructive discussions will contribute to a just, lasting, and mutually beneficial solution, thereby promoting peace, stability, and good neighborly relations between the two countries.

多角的分析
カンボジア経済は、タイとの国境紛争が長引くことで、物流の遅延や国境地域での経済活動の停滞を招くリスクがある。特に、国境貿易に依存する地域経済や、両国間の投資活動に悪影響を与える可能性がある。タイ側の一方的な行動が、地域経済の安定性を損なう要因となりうる。
投資家は、国境紛争の長期化をカントリーリスクとして注視する必要がある。特に、国境地域でのインフラ開発や、両国間でのサプライチェーン構築を目指す投資は、不確実性の高まりにより慎重な判断が求められる。カンボジア政府の外交努力が実を結び、早期に問題が解決されるかどうかが、投資判断の鍵となる。
国境地域に居住する数万人の住民が、境界画定作業の遅延により、自宅に戻れず、生活基盤を失っている状況は、カンボジア社会にとって深刻な問題である。タイ側の一方的な行動が、住民の生活再建を阻害している。この問題の解決は、住民の権利回復と地域社会の安定に直結する。
国境地域に住むカンボジア市民は、タイによる一方的な境界線の主張や占拠、違法行為の継続により、生活の不安を抱えている。境界画定作業の遅延は、住民が自宅に戻り、生計を立てる機会を奪っている。彼らの生活再建と安全確保が喫緊の課題となっている。
背景・歴史的文脈
カンボジアとタイの国境問題は、植民地時代に遡る。1904年と1907年の仏暹条約で多くの国境線が画定されたが、一部地域では解釈の相違や未画定のまま残された箇所が存在する。特に、プレアビヒア寺院周辺の紛争は国際司法裁判所（ICJ）の判断を仰いだが、依然として緊張の火種はくすぶっている。2025年12月のGBC会合で緊張緩和に向けた合意がなされたものの、タイ新政権発足後、カンボジア側はタイの約束履行に懸念を示しており、国境地域での実効支配の拡大や違法行為が問題視されている。
