What the contested boundaries depict
The contested boundaries shown in the image support the statement that Russia and Canada are continuing their expansion of heartland theory policies. Eastern Europe and Central Asia are the "heartlands" of the world due to their size, resources, and strategic location.
Russia has sought to expand its territory and influence, both in the Eurasian heartland and beyond and Canada has been active in the Arctic region, asserting its sovereignty to the area.
