Adilbek Ryskeldiuly Zhaqsybekov (Kazakh: Әділбек Рыскелдіұлы Жақсыбеков, Ädılbek Ryskeldıūly Jaqsybekov) (born 26 July 1954)[3] is current Head of the Executive Office of the President of the Republic of Kazakhstan.

"[6] Zhaksybekov and Abdul Hafeez Sheikh, the Pakistani Minister for Investment and Privatization, signed a trade agreement on 8 December 2003.

The agreement prevented double taxation, and forbid "expropriat[ion], nationaliz[ation]," and "requisitioning" of each other's investments in their respective countries.

Nazarbayev told a news conference in Astana, "Kazakhstan is absolutely interested in developing trade, economic and political relations with Afghanistan, as well as in our joint fight against terrorism and drug trafficking."

Today's visit of the Afghan President is historic, because we meet here for the first time since the statehood of Afghanistan has been restored and the documents we signed are a good foundation for further cooperation."

"[12] On 26 March 2004, Zhaksybekov met with Information Minister Birzhan Kaneshev and Jean-Philippe Courtois, the Microsoft CEO for Europe, the Middle East and Africa, in Astana.

"[13] The Islamic Development Bank, which Zhaksybekov chaired in 2003, agreed to lend the Kazakh government an additional USD $32 million in a meeting in September 2003.

Nazarbayev's political party Nur Otan endorsed Massimov, but some analysts in Kazakhstan considered Zhaksybekov as a candidate.
