But Indians were not caught as Mossad spies. I mean, we have arrested 700 people so far. Nearly all of the foreigners were Afghan, with a few exceptions of people of European origin. Afghans were a major problem for us in this war, not anybody else.
India is not a partner of Iran. People on PDF think they are because of the Chabahar Port, which was first offered to the Chinese, but nobody in Iran considers India to be our partner and our economic ties are very limited now, and our military ties are nonexistent.
China was seen as an alternative in early 2000s, they were given huge projects, thousands of Chinese people lived in Tehran at the time, but it was the Chinese that decided to reduce their ties with Iran over US and Arab money. They even started this by passing 4 rounds of UN Security Council sanctions on Iran, which hurt the Chinese companies who worked with Iran as well. You can't force a country to trade with you if they don't want to.
