2003. Turkmenistan and Russia signed a 25-year agreement on cooperation in the gas sector. Under the agreement, Gazprom Export OJSC and Turkmenneftegaz GTC concluded a long-term contract on export/import of Turkmen natural gas. Over time, Russia increased the capacity of its own production companies and there was no need for Turkmenistan's gas. However, according to experts, Russia was not satisfied with the fact that the gas was supplied to Ukraine and then to Europe.
2006. In January 2006, Azerbaijan Prime Minister Artur Rasizadeh proposes to Kazakhstan Prime Minister Danial Akhmetov that Kazakhstan's gas be exported to Turkey via the South Caucasus Pipeline and from there to the European market.
2007. Russia, Kazakhstan and Turkmenistan sign a trilateral agreement to export gas from Central Asia to Europe via the reconstructed and expanded western branch of the Central Asian Gas Pipeline. This finally puts an end to the Trans-Caspian gas pipeline project, which could have made Turkmen gas supplies to Europe completely independent from the position of Russia and Iran.
2007. In 2007 Gazprom tries to monopolize the Central Asian gas market by offering to pay Kazakhstan, Turkmenistan and Uzbekistan the European gas price of $160/1000m³. The price increase was linked to Russia's attempt to put financial pressure on Ukraine. However, shortly after this offer, "European prices" fell and Gazprom argued that prices in Central Asia should be reduced commensurately. Turkmenistan, however, continued to insist on the European gas price.
2008. Iran's Deputy Foreign Minister states that Iran opposes the construction of any underwater pipeline in the Caspian Sea due to environmental concerns.
2009. The gas conflict between Turkmenistan and Russia unfolds. Until 2009, Turkmenistan exported gas mainly to Ukraine, but then, due to Russian interference, decided to redirect export flows to China. This happened after Turkmenistan accused Russia of blowing up a branch of the Uzbekneftegaz gas pipeline. After that, Turkmenistan signed an agreement with the German energy company RWE AG to transport Turkmen gas to Europe and came to Prague to discuss the implementation of the Nabucco project, a gas pipeline that would connect the EU to Iran via Turkmenistan. Turkmenistan failed to reach an agreement with its European counterparts. Eventually, this year Turkmenistan redirected its gas export flow to China - taking out a loan to build the pipeline and a gas supply contract. Turkmenistan supplies China with about 60 billion m3 annually.
In the same year, the first line of the Central Asian Gas Pipeline appears, bringing gas from Central Asia to China. The first line appears in Turkmenistan.
2010. Turkmenistan agrees to reduce supply volumes for Russia. Volumes are reduced to 10 billion m3 at a price of $200-250 per m3.
2014. Turkmenistan continues to look for new gas markets. The country is focused on trade with the EU, but transportation requires a Trans-Caspian gas pipeline, the construction of which requires the consent of all countries in the Caspian basin. Russia and Iran remain opposed to the construction. Officially they protest "for environmental reasons," but in reality, analysts say, Russia does not need a competitor in the European market, and Iran needs Turkmenistan's gas.
This year, China is completing a plant to prepare marketable gas at the Bagtyyarlyk site in Turkmenistan, where CNPC produces gas and sends it through the Central Asian gas pipeline.
2015. Turkmenistan claimed that Russia stopped paying its debts due to the imposed sanctions. Russian representatives accused Turkmenistan of "hysteria" and slander. Turkmenistan's media later stated that the experts were trying to destroy relations between "brotherly nations".
2017. Gas supplies to Iran are stopped - the latter delayed payment.
2019. Gas supplies from Turkmenistan to Russia are restarted. According to insiders, Turkmenistan had to "make serious concessions in the price to the Russian monopolist". The statement was made on the day the Turkmen government canceled gas, electricity, water and table salt benefits for 5.7 million citizens. According to an unnamed expert, the decision is related to the signing of the Caspian Convention.
"On August 12, the Caspian Convention was signed. In terms of security issues, Moscow ensured non-interference of outside forces in the Caspian Sea, but it had to make some concessions on the issue of the Trans-Caspian gas pipeline. At least Moscow has formally left the other member states the option of laying gas pipelines along the Caspian Sea bed. By restarting purchases of Turkmen gas, Moscow will help Turkmenistan in a difficult economic situation and will be able to dissuade Ashgabat from building the Trans-Caspian gas pipeline in the near future, and, most importantly, will make Turkmenistan dependent on Russia's own gas exports".
2020. Russia announced that it has doubled its gas imports from Turkmenistan. Representatives of Turkmenistan's Fuel and Energy Complex said that Russia's plans to build the Power of Siberia-2 gas pipeline to China is an attempt to force Turkmenistan out of the Chinese gas market.
