It depends on who you ask. In America, the Thai dipping sauce known as Nam Jim Gai (Chicken dipping sauce AKA Sweet Chili Sauce) is popular enough that it can now be found in local grocery stores. Nam Jim Satay AKA Peanut Dipping Sauce is also quite popular in the West. In Thailand, Nam Pla Prik (Fish sauce with chilis) is a seasoning sauce found ubiquitously on every table, in restaurants and in homes.
