"Intelligence directors from Russia, China, Iran and Pakistan met on Tuesday to discuss regional cooperation with particular reference to combating the Islamic State in Afghanistan. Information about the high-level meeting was revealed yesterday by Sergei Ivanov, media spokesman for the Russian Foreign Intelligence Service (SVR). Ivanov told Russia’s state-owned TASS news agency that the meeting was held in Pakistan and included the participation of SVR director Sergei Naryshkin. TASS reported that the meeting was held under the auspices of Pakistan’s powerful Inter-Services Intelligence (ISI) Directorate and was attended by “senior intelligence officials” from Pakistan, Russia, Iran and China..."
Pakistani agencies (including ISI) had many organisational and personal links with al Qaeda and, of course, the Taliban from the 1980s to the 2000s, but Pakistani agency links with Islamic State have not yet matured. This is partly because Islamic State is more extreme and frequently less venal ie. less bribe-able.
The makeup of the meeting reinforces strategic alliance realities that Pakistan is dependent on China for much missile, nuclear weapons' developments and now submarine building. Meanwhile Iran is dependent on Russia in many respects, including deterring any Boltonesque US-Israeli bombing of Iran.
Overall the meeting recognises China and Russia fear Islamic terrorist attacks as much as Western countries (eg. US, UK, France) as well as India.
