In August and September of 2013, The U.S. was looking to launch a limited attack on Syrian President Bashar al-Assad's targets. Russia intervened, which led to Syria relinquishing control of its chemical weaponry. The Organization for the Prohibition of Chemical Weapons was then tasked with securing and dismantling the weaponry. At the time, "...President Vladmir Putin conceded that he could not be 100% certain that his Syrian counterpart, Bashar al-Assad, would fully give up his deadly weapons stash."
Russia assumed the role of peacekeeper during the Syrian conflict to keep the U.S. from getting too involved, and creating a much larger, international conflict. This was Russia's most notable foreign activity the past year. Russia took position against military intervention, and Syria responded, since Russia is one of Syria's main arms dealers.
