The author appears to hate China and his primary purpose in the article seems to be to drive home that the US and China are equivalent imperialist powers. He doesn't seem to have a strong grasp of a wide range of Marxist and even liberal economic terminology and gets confused in his own arguments. By the author's own admission, the US is the aggressor and has the significant advantage militarily and politically, and the conditions offered by the US would risk destroying party rule in China. That the US has squandered their one time overwhelming economic superiority should not be surprising to Marxists familiar with the US role in the global order and with the tendencies of capitalist development.
It would be useful to contrast the Trump administration's attempt at a 19th century style trade war utilising protectionism mechanisms with the economic sabotage the US used against Japan's booming economy in the 1990s.
The author appears to endorse the call for the overthrow or defeat of the PRC. He also takes the rhetorical stance that China is wrong to exercise protectionist policies and therefore that China should submit to greater exploitation by western imperialists. He characterises his positions on the basis of free market mechanics, positioning them as preferable to centralized planning and even as preferable to keynesian economic controls, a position typically considered right wing even in the US context. He also quotes primarily right wing, primarily US sources such as the economist, brookings institute which is a right wing anti China think tank, a China watcher's blog, and a Georgetown professor interviewed in SCMP.
