<![CDATA[AbstractThailand’s borders with Myanmar, Laos, Cambodiaand Malaysia have been established through amapping process within the framework of theTreaty of Westfalpha. Since the England andFrance left Southeast Asia after World War II,Thailand questioned its borders with itsneighbouring countries and since then the borderissue between Thailand and her neighboursbecame the major issue. The attempts to resolvethe border conflict between Thailand andMyanmar have been conducted through“constructive engagementâ€, and through her policyof “changing battlefields to market placesâ€. TheASEAN approach has been employed in her borderconflict with Cambodia. Cambodia’s attempt toinvolve the UN Security Council has been respondedby the Council to involve ASEAN in its resolution.The failure of the ASEAN approach made Cambodiato submit the issue to the ICJ in The Hague in April2011. On November 11, 2013 ICJ decided thatPreah Vihear and its surrounding area belong toCambodia. The source of the conflict with Malaysiawas not primarily about border, but it was apolitical complaint. The rebellion at the border areawill thus not terminate until the Thai authoritiesunderstand the complaints of the Muslim-Malaysat the border area. The ASEAN mechanism toresolve the inter-state conflict consists of bilateral,trilateral approaches, through the High Council andthe United Nations. The application of stepsbetween Thailand and its neighbours are thebilateral, trilateral steps and the one through theInternational Courtof Justice in The Hague.Keywords: Thailand, Myanmar, Malaysia, Kamboja,ASEAN, Dispute Settlement Mechanism AbstrakBatas Kerajaan Thailand dengan Myanmar, Laos,Kamboja dan Malaysia dibentuk melalui prosespemetaan di dalam kerangka Traktat Westfalia.Ketika Inggris dan Prancis mengundurkan dirisesudah Perang Dunia II, Thailand mempersoalkanperbatasannya dengan negara-negara tetangganya,sehingga perbatasan menjadi pokokpermasalahan.
