(CNN) Canada and Australia will not send athletes to the 2020 Olympic Games in Tokyo because of the risks associated with the coronavirus outbreak, the Olympic committees for both countries said in separate statements.

Both countries' Olympic committees also are calling for the Games to be postponed until 2021.

"While we recognize the inherent complexities around a postponement, nothing is more important than the health and safety of our athletes and the world community," the Canadian Olympic Committee and Canadian Paralympic Committee said in a joint statement Sunday. "This is not solely about athlete health -- it is about public health."

The Australian Olympic Committee's executive board met by teleconference Monday and unanimously agreed that an Australian Olympic team could not be assembled given the changing circumstances across the world, the committee said in a statement.

The committee also said "our athletes now need to prioritise their own health and of those around them, and to be able to return to the families."
