Air Astana (LSE:AIRA), the Kazakh airline group listed in London, Astana and Almaty, has signed a joint venture agreement with China Southern Airlines. The company describes it as the first airline joint venture between Kazakhstan and China, building on an existing codeshare Partnership as flights between the two countries continue to grow.

What Air Astana announced

In a regulatory announcement, Air Astana JSC said it had entered into a Joint Venture (JV) agreement with China Southern Airlines, which is headquartered in Guangzhou. Air Astana, together with its low-cost Subsidiary FlyArystan, forms the Air Astana Group.

According to the release, the agreement is the first airline JV between the two countries and builds on the carriers' existing codeshare partnership. The announcement points to cooperation on coordinated flight schedules, expanded codeshare services and joint marketing.

The release does not set out the ownership structure, revenue-sharing arrangements, financial terms, regulatory approvals or an effective date for the JV.

Background: from codeshare to joint venture

Air Astana and China Southern signed a codeshare agreement in July 2025. At the time, the arrangement covered routes including Almaty to Beijing, Urumqi and Guangzhou, and Astana to Beijing on Air Astana's side, with China Southern flights to Almaty and Astana from cities including Guangzhou, Urumqi and Xi'an.

Under the current network described in the announcement, Air Astana operates from Astana and Almaty to Urumqi, Beijing, Guangzhou and Shanghai, with up to 36 weekly return flights in peak season. China Southern operates from Urumqi, Beijing, Guangzhou and Xi'an to Almaty and Astana, with up to 29 weekly return flights in peak season.

Why the China market matters

The announcement highlights rapid growth in air links between the two countries. Scheduled flights between Kazakhstan and China rose 52% compared with the same period in 2025, to 117 per week across 21 routes, and more than one million passengers have been carried since the start of 2026.

Richard Ledger, Vice President, Partnerships and Alliances at Air Astana, said: "China is a strategically important market for Air Astana,". Zeng Yongchao, Executive Vice President of China Southern Airlines, said: "This joint venture is a substantive achievement in aviation connectivity between the two countries".

The release also quoted Talgat Lastaev, Deputy Minister of Transport of Kazakhstan: "The Ministry plans to further expand the route network with China, increasing it to 30 destinations,". For LSE stocks with emerging-market exposure, this policy backdrop matters.

Risks and open questions

Because the announcement does not disclose financial terms, it is not possible to assess from the release alone how the JV may affect Air Astana's Revenue or margins. Airline joint ventures can depend on regulatory clearances, and the announcement does not state whether any approvals are still required.

More broadly, airline Earnings can be sensitive to fuel costs, currency movements, aircraft availability and geopolitical factors affecting routes. Growth in Kazakhstan–China traffic, while rapid in 2026 according to the company, may not continue at the same pace.

What investors may watch next

Investors may look for further detail on how the JV will operate, including any revenue-sharing model, the routes covered and the start date. Future trading updates and traffic statistics from Air Astana (LSE:AIRA) may show whether capacity and passenger numbers on China routes continue to rise, and whether further destinations are added as the ministry plans.

A step deeper into China for a London-listed airline

The agreement deepens an existing partnership into what both carriers describe as a joint venture, at a time of rising flight numbers between Kazakhstan and China. For the UK stock market, Air Astana remains one of a small group of London Stock Exchange-listed companies offering direct exposure to Central Asian aviation, and the JV adds a new strategic element to that profile.
