The domestic political situation of Tajikistan in 2015 was stable in general，under the firm control by its president. The parliament of the two houses held the election smoothly，ending in prevention of the opposition party from entering the parliament. The armed attack incident plotted by the vice minister of defense was promptly put down，and the Islamic Renaissance Party was cracked down. Economically speaking，Tajikistan’s economic growth slowed down. Its foreign trade，overseas remittance and exchange rate dramatically shrank as a result of the adverse influence of the Russian economic sluggishness. As for security，due to the Afghan northern situation，the threat on the Tajik northern border with Afghanistan was increasing，with the tendency of the thought current of the Islamic Extremism becoming active. Diplomatically speaking，Tajikistan made certain breakthroughs in bilateral relations with each of the three countries：Kazakhstan，Ukraine and Kyrgyzstan，and stabilized and progressed its relations with powers beyond its region. Tajikistan positively participates in various SCO activities，putting expectations on economic and security cooperation with the SCO.
