Early life and ministry Kitbunchu was born in Sam Phran, a district of the Nakhon Pathom Province, to parents of ethnic Chinese descent and studied at the minor seminary of Si Racha. He then furthered his studies at the Pontifical Urbaniana University in Rome, where he obtained a licentiate in both philosophy and theology. While in Rome, he was ordained to the priesthood by Cardinal Grégoire-Pierre Agagianian on 20 December 1959.

He returned to Thailand and served as assistant pastor and then pastor in Bang Kham, and later became pastor of Calvary Parish in Bangkok. He once expressed his opposition to abortion by saying, "Abortion is a great crime, because the one who should protect the child in her womb becomes the one who destroys the child."

During the 2006 political crisis in his Thailand, Kitbunchu called for unity, saying, "All Thai people are patriotic and want the country to progress and develop on all fields, but now the political crisis has disturbed and worried the people." He also asked Thais to "correct what is wrong and forgive each other."

Kitbunchu resigned from his position as Archbishop of Bangkok on 14 May 2009. At the time of his retirement, he was the oldest active head of an archdiocese in the Latin Church. In addition to his native language, Central Thai (official and national) and his ethnic Chinese dialect of Teochew, he can also speak other languages such as Latin, English, Italian, French and Standard Mandarin.

From the death of Roger Etchegaray in 2019, Kitbunchu and Alexandre do Nascimento were tied as the longest-tenured members of the College of Cardinals, both having been appointed in 1983. After do Nascimento's death on 28 September 2024, Kitbunchu became the sole longest-tenured member of the College.
