The East Turkistan Islamic Movement (ETIM), a terrorist organization that has planned and carried out a series of violent terrorist attacks both inside and outside of China, has increased its connections with international and regional terrorist forces such as the Islamic State (IS) and Al-Qaeda, posing a serious threat to China's overseas interests and the security and stability of relevant countries and regions, Chinese Foreign Ministry spokesperson Wang Wenbin said at a press conference on Thursday, stressing that combating ETIM is China's core concern in counter-terrorism and shared responsibility of the international community.
