There is an easy explanation here.
We all know Arab states are British/American creatures, so the way to view their actions is in that context.
One of the points about alleged Arab friendliness to Pakistan is the past and old gestures.
Well REMEMBER - Pakistan used to have good relations with the west because Pakistan fought the wests war in Afghanistan, hence the gulf helped Pakistan.
Now, west is against is, therefore gulf states will fall in line, remember they are creatures, useful to function as the CIA mi6 Islamic patsies, hosted and paid for by Saudi.
The Arab gulf states have been a conduit for American actions, so kindness or bad actions, always puppets!!
This is all the part of the new game, orchestrated by the new rulers (carpetbaggers) of the world.
They pose China and Pakistan as a threat to India to make Indians as their foot soldiers against these nations.
They pose Iran as a threat to Saudi Arabia and Gulf states to sell them their weapons and keep their resources secure.
They pose Gwadar/Karachi as threat to Gulf emirates to use them as a conduit of terrorist financing in Pakistan.
Few decades ago, US used Saudi money in the same way by presenting USSR as an existential threat to their oil and religion. Even if Saudi Arabia is not directly involved in terrorist financing in Balochistan, it's gesturing shows how it is working as a puppet of US. Here Saudis are warming up to India for joint armament production and research, there they are handing over a 'Wanted Pakistani Terrorist' to India.
The situation may look bleak but it can be turned into an opportunity by co-operating with the nations who think that they have a
stake in the region. Co-operate with China to make the dream of Western China - Gwadar trade corridor a reality. This will automatically bring prosperity and security in the region. Strategic alliances with Russia & Iran will also act to counter-balance the negativity that is being sown in our minds. Keyword - SCO.
Yes, Peninsular Arabs are our Muslim brothers, but our real life (biological) brothers will also be
more faithful to their business partners than their actual brothers. The largest customers of Gulf oil happen to be US and it's allies. All the oil wealth is then again invested in to US and (mainly) Western nations. The private Saudi investments in USA totaled $400-800 Billion. We can not blame Arabs for everything, we need to bring our house in order first to merit their attention and investment. Just like the real brothers, they still come to our rescue in the times of need (earth quakes/floods/other disasters etc). Once we get better, I am sure trust levels (and a positive co-operation) will increase, Insha Allah.
