[3][4] On 9 December 2024, Arakan Army captured all of the Burmese military outposts and seized control of Myanmar's border with Bangladesh.

From the 1820s-80s, Britain also gradually conquered Burma; by the Treaty of Yandabo in 1826, which ended the First Anglo-Burmese War, Burma recognised British control over Assam, Manipur, Rakhine (Arakan), and the Taninthayi coast, thereby delimiting much of the Indo-Burmese modern boundary in general terms.

In a flag-meeting between the border forces of the two countries, Myanmar regretted the killing and admitted that they had mistaken the patrol for Rohingya separatists.

[23] In February 2024, during combat between Arakan Army and BGP, at least 264 Myanmar military personnel sought refuge in Bangladesh, where they were disarmed and sheltered by the BGB.

[24] In mid-January 2025, the Arakan Army seized three cargo vessels on the Naf River that were transporting goods from Yangon to Teknaf port in Cox's Bazar, Bangladesh.

These vessels were carrying approximately 50,000 bags of dried fish, betel nuts, coffee, and other products, with an estimated value of Tk 40 crore.

There have also been a number of incidents over the years involving fishermen on the Naf river allegedly illegally crossing the boundary.
