most naitons are against us sanctions on Iran and on some occasions even india also voted against Iran.
For example these are words of former Indian PM rao, we do not need another islamc country with nuke capability in a meeting with the delegation lead by delhi imam moque. this reflects policy. the good relations are busines and commercial.
The business and commercial ties are better as india needs oil and iran provides. india even planned to lessen its dependency on iran's oil jsut sometimes back and buy iraq. the relations are typically commercial.
If there is will it can be done at the earliest instead of years or decade.
Mr. Rao is known for his positive diplomacy on Iran!! India did not join the western chorus on Iranian ‘non-compliance', India was keen that Iran should resolve its differences through negotiations within the IAEA. It was in the very same year India built the chabar port
