The Outer Space Treaty of 1967

I was reading an article about China’s space station that will soon fall out of orbit back into earth’s atmosphere; LINK
then, I can came across “the outer space treaty”

According to international space law , China is responsible for any damage sustained to an individual or his property anywhere in the world should scraps of its space station fall on land, according to Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space , or The Outer space Treaty.

Another relevant clause in the treaty is that it bars countries from putting weapons of mass destruction into orbit or installing them on the moon.
