The Chinese government should probably take this opportunity to finally get Iran out of the Russian sphere of influence. They've already snatched Venezuela from you, and the rest of the South American will steadily fall one by one. Getting Iran will be a trump card. I'll tell you, the arabs are stooges and vassals - they are worthless and in my view very expendables, just like the indians. By walking a tight rope between them and the Persians, you're setting yourself up for failure. Let Iran and Pakistan play the good cop bad cop for your policy across the greater Middle East and South Asia.
