China doesn't care if it loses thousands or millions of its people. They sure as he'll don't care about killing off other nations residents either.
They lend developing nations or pay for the construction of infrastructure, but in the process take huge chunks of land/ resources etc... and then move in their own people to setup huge business that will only employ Chinese.
They are doing it in the Carribean, Africa, and South America. They opened up tons of Chinese immersion schools in the USA indoctrination children at the elementary school stages to Confuscionism and other Chinese propaganda throughout the USA. Meanwhile multiple news outlets chastise or shame anyone who calls them out for a virus they created.
