So? Did Iran ever complain why you provided Shamsi airbase to UAE and US? Did Iran ever complain that Arabs roam around in Pakistani Balochistan under the excuse of "hunting birds" but who knows what games they are playing there? Did Iran ever complain about these games:

Get your act together. If you are worried about separatism there, then by all means, crack down there. Iran has been complaining over lax security on Pakistan's part. It is the Shia Hazara who are being targetted there in a genocide. Stop that. You know where support for these comes. Not from Zahedan.
Get your act together. If still it bothers you, you can go ahead an allow Saudis to open up a consulate there. That is your sovereign right. Exercise it. As Iran has exercised it. And that Indian consulate there, actually is part of Iran's effort to become a trade route to Central Asia via Chabahar and to Europe. It has nothing to do with your conspiracy theories. Iran even helped Pakistan to develop its Gwadar port, believing in healthy competition so much so that the Gwadar is not connected to Pakistan national electric grid. It is connected to Iran's national electric grid. Furthermore,
Iran even offered to build a refinery and oil pipeline to Gwardar in order for you to be able to refuel the visiting ships. Pakistan refused.
Get your act together. Conspiracy theories will not take you far.
And please do not derail this thread.
