Alliances shifting fast

Saudi Arabia and Pakistan moved from a long-running partnership to a formal mutual-defense pact on September 17, 2025, and Pakistan put that pact into visible use on April 11, 2026. (spa.gov.sa; aljazeera.com) The Saudi Press Agency said Crown Prince Mohammed bin Salman and Prime Minister Shehbaz Sharif signed a Strategic Mutual Defense Agreement in Riyadh stating that aggression against one country would be treated as aggression against both. (spa.gov.sa) Al Jazeera, citing the Saudi Ministry of Defence, reported that Pakistani fighter and support aircraft landed at King Abdulaziz Air Base in Saudi Arabia’s Eastern Province on April 11, 2026, during a fragile April 7 ceasefire after the regional war that began on February 28. (aljazeera.com; imf.org) Turkey’s shift is less about a defense treaty and more about denser political and economic links with China. Ankara’s own foreign ministry says relations were elevated to “Strategic Cooperation” in 2010, and that President Recep Tayyip Erdoğan last met Xi Jinping at the Shanghai Cooperation Organization summit in Tianjin on August 31, 2025. (mfa.gov.tr; mfa.gov.cn) China’s foreign ministry said Xi and Erdoğan discussed aligning the Belt and Road Initiative with Turkey’s Middle Corridor, while Erdoğan said Turkey wanted more trade, investment, infrastructure and new-energy cooperation with China. (mfa.gov.cn) That economic turn already has a factory attached to it. Turkey’s investment office said on July 9, 2024 that BYD signed a $1 billion agreement to build a plant and research center in Turkey with capacity for 150,000 electric and plug-in hybrid vehicles a year, up to 5,000 direct jobs, and production due by the end of 2026. (invest.gov.tr) The two pairings sit inside the same pressure system: energy routes, war risk and supply-chain exposure. The International Monetary Fund said this month that the Middle East war that erupted on February 28, 2026 pushed the Strait of Hormuz, which normally carries roughly one-fifth of global oil supply and about one-quarter of global liquefied natural gas trade, close to a standstill. (imf.org) That helps explain why Riyadh is tightening hard-security ties while Ankara is widening trade and transport options. China’s foreign ministry said Beijing wants progress on the China-Europe Railway Express southbound passage, and Turkey’s foreign ministry says 2026 marks 55 years of diplomatic relations between the two countries. (mfa.gov.cn; mfa.gov.tr) The Saudi-Pakistan track also carries a nuclear shadow because Pakistan is a nuclear-armed state and Saudi Arabia is not. Analysts have debated for years whether closer Saudi-Pakistani defense ties could sharpen deterrence signaling toward Iran, though the pact text released by Riyadh speaks in general terms about joint deterrence and does not mention nuclear cooperation. (spa.gov.sa; mei.edu) Neither shift means old alignments disappeared. Saudi Arabia still depends heavily on U.S. security ties, and Turkey remains a North Atlantic Treaty Organization member even as it expands business and diplomatic channels with China. (mfa.gov.tr; washingtoninstitute.org) What changed is the speed and the form: Riyadh locked in a written defense commitment with Islamabad, and Ankara kept adding leader-level meetings, transport planning and Chinese industrial investment. In a year shaped by war around Gulf energy routes, countries that once hedged quietly are now putting more of those bets on paper. (spa.gov.sa; mfa.gov.cn; invest.gov.tr)
