So telling from this little blurb:
"China has decided it has nothing further to fear from the Trump administration, and has decided to incorporate Iran into its One Belt, One Road plan with investments totaling some $400 billion. So says Simon Watkins, writing at Petroleum Economist.
I suspect Iran would rather have had this deal with Europe, but Trump breached the 2015 Iran nuclear deal and slapped severe sanctions on Tehran, and has been bullying big European firms into joining the financial blockade. Iran had to seek its economic future with China, whether it likes it or not."
