Why are 45 countries in joint-military exercises together? – including US, Russia, and China

More than 45 countries including the world’s top navies will take part in the 7th exercise of the series held every two years since 2007. What makes this year’s exercise more significant is that it brings the three largest navies, US, China and Russia, under one platform for collaborative maritime security. This will be the first time in a decade that Russia will participate in a joint military exercise with NATO members.
