A member of a family of Persian origin,[1] Si Suriyawongse was born the eldest son of Dis Bunnag (Prayurawongse) and Than Phuying Chan. Chuang was well educated for the time. King Mongkut made him Samuha Kalahom (สมุหกลาโหม), one of the two chancellors of old Siam.


Sri Suriyawongse was one of the most important figures in Mongkut's court. As he was the main supporter of Prince Mongkut to be enthroned, he eventually held the position of Samuha Kalahom. He was well known to be a pro-British official, or as a "new generation" among court officials. He was interested in Western learning in various fields such as science, engineering, and steamship building. He had a close relation with Prince Mongkut, the future Rama IV, supporting him in welcoming British influence and Western learning. He also had a positive relationship with early Protestant missionaries, whom he valued for their scientific knowledge and ability to teach English. He was a key figure in promoting the Siam-British relationship, culminating in the Bowring Treaty in 1855, cementing the economic relationship with Britain.

After the death of King Mongkut in 1868, his young son Prince Chulalongkorn became the new monarch. However, as the new king was underage, Sri Suriwongse was named as regent, a post he held until 1873.

He died in 1883 in Ratchaburi. Sri Suriwongse was the first Thai to have a life insurance policy, after King Rama V granted foreign companies permission to introduce their insurance business to Siam.

His son Won Bunnag succeeded him as Samuha Kalahom and also held the title Chao Phraya Surawong Waiyawat.
