Chinese-led Shanghai Cooperation Organisation 'ready to act in Kazakhstan if needed'

The Chinese-led Shanghai Cooperation Organisation has vowed to intervene in the Kazakhstan unrest if needed, but also backed the Kazakh government's actions - a sign of approval for Russia's intervention.

The pledge from the group came as US Secretary of State Antony Blinken warned that Kazakhstan would find it difficult to reduce Russian influence after inviting in troops to quell unrest.

Following days of violence, Kazakhstan's domestic intelligence agency said its former head Karim Mosimov had been detained after it launched an investigation into charges of high treason. Mosimov was sacked earlier this week.

The initial cause of the protests was a spike in prices for compressed gas in the country's western energy heartland, but President Kassym-Jomart Tokayev said the protesters are "bandits and terrorists" and authorised his forces to shoot without warning.

Tokayev also appealed for help from the Russia-dominated Collective Security Treaty Organisation (CSTO), which consists of six post-Soviet states.

Russia's defence ministry said nine planes carrying paratroopers and hardware had landed in Almaty and its forces had helped to secure the airport.

The Shanghai Cooperation Organisation's regional anti-terrorist structure said it is ready to extend assistance to Kazakhstan "if there is a corresponding request from Kazakhstan's relevant body," Russia's TASS news agency reported.

But it added that it is convinced that the current actions taken by Kazakhstan will help stabilise the situation as quickly as possible, saying: "[The Executive Committee] expressed all-round support for the resolute comprehensive measures taken by the country's leadership to ensure public security and protect the constitutional system of Kazakhstan".

In a separate statement, Zhang Ming, the secretary general of the group, whose members include Russia and Kazakhstan, said he hoped the situation will soon stabilise.

"Maintaining internal stability and social harmony in the republic of Kazakhstan as a member state of SCO is one of the key factors for peace and security in the region," Zhang said.

The violence erupted late Tuesday, when police fired tear gas and stun grenades at a thousands-strong protest in Almaty.
