This is a terrible deal for regional power in Asia.
The aim of TPP was to eventually force China to the table to play by TPPs rule while giving developing economies a carrot to follow international trade rules and workers rights with open access to the US, Australia and Japanese markets along with investment in infrastructure.
Now China will continue to use Cambodia and now the Phillipenes to blunt any efforts by the ASEAN to blunt Chinese influence in the region.
This is bad for America, bad for the region, bad for the global environment, bad for US patent holders and will do nothing to stave off automation.
But, free trade, globalism and pluralism are now dirty words from a chunk of both sides of the aisle so here we are taking a rusty knife to our collective faces cheering the removal of our nose.
Cambodia and the Philippines were not part of the TPP.
The TPP did not drastically do anything new that wasn't in China's free trade agreements with, for instance, South Korea or Australia. The geopolitical hope that the carrot of more trade would force China to sign side agreements in order to join TPP is not very specific enough. There was nothing specific except saber rattling such as "cannot allow China to set the rules" but the TPP would not have staved of the RCEP, which had already had 16 rounds of negotiations before the election.
There is nothing in TPP really that would have staved off automation. I do not think it had much in there for environmentalism as well. There is nothing in TPP that would provide for investment in infrastructure--the Chinese Belt-and-Road initiative and AIIB is more specifically geared towards infrastructure investment in Asia.
If you really want to go into the specifics of TPP and the various changes schedules to the changes in duty rates, but TPP has been put on a pedestal for the things that it would accomplish for America. The CAFTA and South Korea FTA did not do much for America in terms of geopolitics either, even though the latter especially was framed as an accomplishment of the Asia pivot.
