On March 31, 2007, the 20th Congress of the Halk Maslahaty began in the city of Mary. New laws relating to agricultural efficiency were passed, and it was decreed that school teachers' wages would soon rise by 40%. On May 12, Russia and Turkmenistan announced that they had reached an agreement to build a new natural gas pipeline from Turkmenistan to Russia, via Kazakhstan. This has led to speculation that the European Union will become more energy-dependent on Russia, which buys Turkmen gas at below-market prices, and that as a result Russia's political influence in Eastern Europe may increase.

In 2008, Berdimuhamedow restored the Latin-based names of the months and traditional Persian and Turkic days of the week (Niyazov had renamed them after himself and his mother, among other things), and announced plans to move the infamous gold rotating statue of Niyazov from Ashgabat's central square.

Parliamentary elections under this new constitution were held on December 14, 2008. In December 2008, Berdimuhamedow announced changes to the national anthem, which involved removing the repeated references to former President Niyazov.
