Berdymukhamedov dismissed the officials for "serious shortcomings" at a yesterday meeting of the secretive country's cabinet of ministers, an article posted on the state-run Turkmenistan.Ru website said.
The sacked senior officials were economy and development minister Eldash Sheripov, trade minister Bayar Abayev and tax service chief Shatlyk Khumedov.
Sheripov and Khumedov were replaced respectively by former subordinates Batyr Bazarov and Saperberdy Gundogdiyev, while ex-Chamber of Commerce head Dovran Orazmyradov has replaced Abayev as tax chief.
Last year the all-powerful leader issued a call for greater economic diversification, in a rare admission of the national economy's over-reliance on oil and gas revenues that make up 90 per cent of exports.
