The United Theravada Bhikkhuni Sangha International (UTBSI) was officially formed on November 19, 2021. The person behind is was Ven. P. Seewalee, Secretary General of Maha Bodhi Society of India. He provided the space to allow the bhikkhunis to come together.

The most senior monastics who participated were:

Ven. Tathaaloka from United States
Ven. Santini from Indonesia
Ven. Lieu Phap from Vietnam
Ven. Dhammananda from Thailand
Ven. Bodhicitta a Sri Lankan bhikkhuni from Australia
Ven. Sumangala from Malaysia
Ven. P. Seewalee, MBSI

Prior to the formation of UTBSI, the Asian bhikkhunis were already united as the Network of Theravada Asian bhikkhunis. They supported each other at the very beginning in forming a sangha in their own country. But with UTBSI, Ven. Tathaaloka from the United States joined in as another coordinator, thus it has become not only Asian but now International. These bhikkhunis are working together as co-ordinators along with Ven. Dr. Lieu Phap (from Vietnam) as secretary. The output of this group of bhikkhunis is really outstanding.

In 2022, alone they organized many Buddhist events which allowed people to have access to the Dhamma in a profound way. The UTBSI is still at its early stages and although the bhikkhunis are busy with their own responsibilities and their own monasteries, they still come together under UTBSI in the attempt to make a good impact on society as a whole.
