Chad supports (key ally) RSF too and pretty sure Wagner/Russia do as well. At least they did for a very, very long time.
Haftar did as well earlier but it seems that he has been reigned in with the prospect of Libya finding a political solution as well.
KSA and Egypt (UAE and USA ironically too - part of the quartet) are actively trying to broker peace. KSA did it once before in Sudan (after the fall of the Al-Bashir regime - which created most of the problems today) but both parties broke this when they (Al-Burhan) made a coup in 2021 against the transitional council as I covered earlier in this thread.
KSA already brokered the 30 + years old "cold war" between Ethiopia and Eritrea.
Extensive KSA-Egypt (we are the direct neighbors of Sudan and have the most influence politically on the ground - closest relatives to Sudanese people too in every sphere) military meetings have taken place in recent weeks connected to the situation in Sudan.
Ongoing military exercises too:
"Saudi Ministry of Defense:
Launch of "Red Wave 8" exercises with international participation to bolster Red Sea security and protect vital maritime passages, in affirmation of Saudi Arabia's pivotal role in safeguarding energy security and global trade stability."
Ideally someone, somehow, will be able to reign in Abu Dhabi and MbZ. They have gone rogue. In fact it was already seen during their destructive role in Yemen when they began supporting the Southern separatists weakening KSA/Yemeni government attempts at unifying Yemeni ranks.
Bin Zayed (the father) was such a good and well-respected Arab leader across the entire Arab and Muslim world. How his son/UAE could take such a turn for the worse, is hard to explain and it pains me, because the average Emirati (which is a brotherly people regardless of their rulers) does not support such policies. But they (regime in power) are the darling of the Jews/West/have great ties with even Russia and China, so hard to do something.
Again, in a perfect world, KSA would annex/merge with all of those small GCC states, but nobody would want to see such a country turn into the richest in natural resources overnight (even richer than Russia).
This was already the case 35 years ago when Saddam invaded Kuwait. Nobody in the West cared about Kuwait the country but they were afraid of Saddam conquering all of Eastern Arabia and controlling most of the world's oil, gas and some of the most strategic trade/sea routes.
Everyone involved in Sudan is also in it to gain favors with the winning party because Sudan has the most fertile land in the Muslim world and is a country rich in resources and will have a huge population in the future like most Arab countries. It sits strategically too connecting various parts of Africa (North, Sahel, Horn of Africa and Sub-Saharan Africa going south towards South Sudan). Not to mention the very strategic Red Sea. Before the North/South split, Sudan was the largest African country too.
