The Ukraine-Russia conflict began in 2013 when Ukrainian president Viktor Yanukovych decided not to sign a trade deal with the European Union and instead accepted a Russian bailout, sparking mass protests. In 2014, Yanukovych was removed from office by parliament and fled to Russia. Russia then seized control of Crimea and backed separatist rebels in eastern Ukraine. The US and EU imposed economic sanctions on Russia in response, and tensions escalated further after MH17 was shot down over eastern Ukraine. Ukraine remains divided between pro-Russian eastern regions and the west which favors integration with the EU, while a resolution to the ongoing conflict remains elusive.
