I think that the Russians are just stringing the Iranians along. The fact that the Iranians are poking Israel and the US in the eye is just a bonus for them. China has no interest in helping the US or Russia so they are just sitting off on the sideline eating popcorn.
Russia and China have been holding joint war games every other year since 2005. The latest took place on July 22-27 of last year.
"Russia and China will hold their joint military exercise on July 22-27 on the territories of the two countries. About 3,000 military men, 300 units of military hardware, over 40 planes and helicopters will take part in Peace Mission-2009 drills. About 1,500 servicemen, T-80 tanks, BMP-1 and BTR-70 armored vehicles, 22 aircraft, including two Il-76 cargo planes, five Su-24, five Su-25, five Su-27 fighters and five Mi-8 helicopters will represent Russia in the drills."

 Russia, China plan new joint military exercises

WASHINGTON, March 26 (UPI) -- The continuing tensions over Russia's refusal to sell its state-of-the-art land warfare advanced weapons systems to China hasn't interrupted the rhythm of major joint military exercises between the two major land powers on the Eurasian landmass. The latest in the regular, biennial series of exercises between the two nations has been confirmed for this summer.
The next in the now well-established series of exercises called Peace Mission 2009 will be carried out in northeastern China, the Russian Defense Ministry announced March 18, according to a report carried by the RIA Novosti news agency.
The first bilateral Peace Mission maneuvers -- described at the time as counter-terrorism exercises -- were held in Russia and the eastern Chinese province of Shandong in August 2005. As we reported at that time, they were a lot bigger than mere counter-terrorism exercises. Warships, squadrons of combat aircraft and more than 10,000 troops were involved carrying out landings against hypothetically hostile shores. The maneuvers also involved large-scale paratroops drops. The scale and nature of those exercises suggested a trial run for a possible Chinese invasion of Taiwan with Russian support. ..."
Russia, China flex muscles in joint war games

CHEBARKUL, Russia (Reuters) - Russia and China staged their biggest joint exercises on Friday but denied this show of military prowess could lead to the formation of a counterweight to NATO.
"Today's exercises are another step towards strengthening the relations between our countries, a step towards strengthening international peace and security, and first and foremost, the security of our peoples," Putin said.
Fighter jets swooped overhead, commandos jumped from helicopters on to rooftops and the boom of artillery shells shook the firing range in Russia's Ural mountains as two of the largest armies in the world were put through their paces.
The exercises take place against a backdrop of mounting rivalry between the West, and Russia and China for influence over Central Asia, a strategic region that has huge oil, gas and mineral resources.
Russia's growing assertiveness is also causing jitters in the West. Putin announced at the firing range that Russia was resuming Soviet-era sorties by its strategic bomber aircraft near NATO airspace.
War Games: Russia, China Grow Alliance
September 23, 2005
In foreign policy its critical to know thine enemy. So American policymakers should be aware that Russia and China are inching closer to identifying a common enemy the United States.
The two would-be superpowers held unprecedented joint military exercises Aug. 18-25. Soothingly named Peace Mission 2005, the drills took place on the Shandong peninsula on the Yellow Sea, and included nearly 10,000 troops. Russian long-range bombers, the army, navy, air force, marine, airborne and logistics units from both countries were also involved.
Moscow and Beijing claim the maneuvers were aimed at combating terrorism, extremism and separatism (the last a veiled reference to Taiwan), but its clear they were an attempt to counter-balance American military might.
Joint war games are a logical outcome of the Sino-Russian Friendship and Cooperation Treaty signed in 2001, and reflect the shared worldview and growing economic ties between the two Eastern Hemisphere giants."
From the Sino-Russian Joint Statement of April 23, 1997:
"The two sides [China and Russia] shall, in the spirit of partnership, strive to promote the multipolarization of the world and the establishment of a new international order."
