art. Painted thankas, paintings in manuscripts and small bronzes are typically the finest forms of Tibetan art. One of the most characteristic creations of Tibetan Buddhist art are the mandalas, diagrams of a "divine temple" made of a circle enclosing a square, the purpose of which is to help Buddhist devotees focus their attention through meditation and follow the path to the central image of the Buddha. These are usually temporary, laid out on a floor for a festival, then swept away. In 10th to 11th centuries, Tabo Monastery in Himachal Pradesh, Northern India (at that time part of Western Tibet Kingdom) serves an important role as an intermediary between India and Tibet cultural exchange, especially Buddhist art and philosophy. Notable example of Tibetan Buddhist art in Tabo is its exquisite frescoes.

This demand revived the sea connections between the Mediterranean Sea and China, with India as the intermediary of choice. From that time, through trade connections, commercial settlements, and even political interventions, India started to strongly influence Southeast Asian countries. Trade routes linked India with southern Burma, central and southern Siam, lower Cambodia and southern Vietnam, and numerous urbanized coastal settlements were established there.
