Over the past six years, the Syria conflict in some areas tended to cool down. President Trump reached an agreement with Russian President Putin on building a new ＂conflict relegation zone＂ on July 7, 2017. After three years of hard fighting, Iraq liberated Mosul on July 9, 2017. Full restoration of territorial integrity is just around the comer. ISIS lost Mosul, and was trapped in Racca. Further loss of land and territory is just a matter of time.展开更多

These statements provide important theoretical guidance for us to better understand the historical position of socialism with Chinese characteristics and gain deep insights into the historical and logical correlation between socialism with Chinese characteristics for a new era and the world socialism.展开更多

To a large extent, the problem can be traced back to the ＂power-property＂ system established by Ivan IIL That is to say, the possession of power is equivalent to the possession of property, and property becomes certain functions of power. For a long time, this system has been accepted as a natural state of society by the Russian people. Rapid economic growth under the Putin administration is characterized by the return to and strengthening of a ＂power- property ＂system dominated by the state and an abandonment of ＂institutional transplantation＂ from the Western liberal market economic model in the Yeltsin era under which power and property were separated Mr. Putin＇s reelection in 2012 means that the ＂long-Putin era＂ that started from 2000 will last at least until 2018. However, with the solidification of the ＂power- property＂ system, the Putin administration has been confronted with new challenges, and the prospects for Russia＇s economic modernization still face great uncertainties.展开更多
