The Treaty of Yandaboo was signed by Gen. Campbell from the British side and Governor of Legaing Maha Min Hla Kyaw Htin from the Burmese side on 24 February 1826. The Burmese paid 250,000 pounds sterling in gold and silver bullion as the first instalment of the indemnity, and also released British prisoners of war.

Some of the pre-conditions that led to the signing of the Yandabo Treaty include the British desire for greater control over trade routes and the Burmese desire to maintain their sovereignty and control over their territories. The war had also resulted in significant loss of life and resources on both sides, making it desirable for both parties to negotiate a settlement.

The Yandabo Treaty had several important results. One of the most significant was the cession of Assam, Manipur, and Arakan to the British East India Company. The treaty also granted the British the right to establish trading posts in various Burmese cities, including Rangoon, and ensured that British merchants would be granted fair treatment and protection.

Additionally, the Yandabo Treaty established a fixed boundary between British India and Burma and required the Burmese Kingdom to pay a large indemnity to the British as compensation for the cost of the war. Overall, the treaty marked a significant shift in the balance of power in Southeast Asia, as the British gained a stronger foothold in the region and the Burmese Kingdom began to decline in influence.
