Schiff accused Turkey of inciting the conflict between Armenia and Azerbaijan over the disputed region of Nagorno-Karabakh. He stated that the 2020 Nagorno-Karabakh conflict "must cause us reexamine our relationship with both Turkey and Azerbaijan. If an ally of the United states is recruiting fighters from Syria to encourage further bloodshed and murder of civilians, what kind of ally are they in NATO or otherwise?". Schiff co-signed a letter to Secretary of State Mike Pompeo that read, "We write to express our deep concern with Azerbaijan’s renewed aggression against Artsakh (Nagorno Karabakh) and the rising possibility of a wider conflict with Armenia. We ask that the Administration use all available diplomatic tools to reduce tensions, end the fighting, and restrain Azerbaijan from further offensive actions." Schiff called for U.S. recognition of the separatist, self-declared Republic of Artsakh, which is officially part of Azerbaijan, but has been under control of ethnic Armenian forces backed by Armenia since the end of a separatist war in 1994.
