The four Quad countries – India, the US, Japan, and Australia – will conduct the Malabar 2021 exercises off Guam in the Western Pacific later this month. The Malabar exercise started in 1992 as a bilateral military exercise between the Indian Navy and the US Navy in the Indian Ocean. Japan has been participating in this drill annually since 2015. In 2020, India invited Australia to take part in the annual exercise, making it a drill among the Quad navies.
