This summer’s dispute over undersea Caspian energy resources between Azerbaijan and Turkmenistan, as well as Ashgabat’s recently stated intention to bolster its maritime military capabilities, have seemingly thrown Trans-Caspian relations into a tailspin, jeopardizing plans for energy cooperation to supply the strategic Nabucco natural gas pipeline. Given the Caspian’s delicate geopolitical balance, an international arbitration process on the Azerbaijani-Turkmen dispute may not in fact result in final resolution. That said, developments surrounding the mid-September informal Caspian summit, attended by presidents Ilham Aliyev and Gurbanguly Berdimuhammedov may signal that this Trans-Caspian flare-up will be short-lived.
