For the past two decades, enhanced by China's announcement of new Silk Roads in 2013, the Bay of Bengal (BoB) has been a field of increasing academic and geopolitical interest. Emphasis has been placed on transnational networks and cross-cultural contact transcending current nation-states boundaries to address the shared histories of South and Southeast Asia. Despite this renewed interest, there is still little understanding of the inception and early evolution of the BoB networks. Different historiographic and archaeological traditions in South and Southeast Asian countries make comparisons difficult, and together they only partly explain the early development of the BoB networks. Another difficulty is the need to access, analyse, and compare corpora recovered from different countries bordering the BoB. So far, most comparisons have been made based on morpho-stylistic studies of a few easily identifiable and emblematic types of pottery such as rouletted ware and Arikamedu Type 10. Those are almost always taken out of their local context leaving a wider range of ceramic types unexplored. In this presentation, we discuss some emblematic and other lesser-known Indian ceramic types, as well as locally produced hybrid types, discovered in Peninsular Thailand and Myanmar, in the frame of research carried out by the French archaeological mission in Peninsular Thailand-Myanmar since 2005, led by B. Bellina. The ceramics are from multiple sites ranging from the 5 th century BCE to the early centuries AD. We propose to broaden the study of early exchanges in the BoB by placing these ceramics into their local contexts to produce a more integrated understanding of the interactions which, beyond Indian traders, also involve many other groups in the Bay of Bengal.
