I have learned that Iran sanctions are not new but was intensified (maybe/maybe not for good) by Prez Trump's administration. Relations with China too was with ups and downs if we see it historically.

Recently, Trump administration has imposed new sanctions on Iran.

And delisted East Turkestan Islamic movement from Terrorist List. This angered China!

East Turkestan Islamic Movement was listed by President Bush who was republican. This is relevant, please read till the end.

If I see things from a bird's eye view I feel:

1. US had a gradual improvement in foreign relations with countries with which it didn't have very good relations in the past.
2. Or, US improved situations where it needed.
3. Or, destroyed what it needed to destroy. (Take the last sentence in a lighter note)

Media will give opinions. Russian media will have its own opinion. Chinese will have theirs. Others will have others.

Honestly, I wanted to ask "How would new sanctions imposed by a lame duck president hamper the new president in case of the USA?". If I did so, there was a good chance that it would have been deleted, so I am trying to make it appropriate. Tried my best! Change the body appropriately if necessary.

Does US' foreign policy depend upon the party or does it have a special board that recommends it what is best irrespective of the ruling party?
