Jabarkan Karier Politik dari Sanjaagiin Bayar

Bayar bergabung dengan Partai Rakyat Revolusioner Mongolia (MPRP) pada tahun 1988. Dia menjabat Sekretaris Jenderal MPRP tahun 2005 dengan meraih 377:229 suara dan terpilih menjadi Ketua MPRP pada kongres partai tanggal Oktober 2007 ketika mengalahkan Miyeegombyn Enkhbold yang saat itu sedang menjabat. Pada Kongres yang sama, dia juga mendapat dukungan untuk menjabat Perdana Menteri berikutnya.

Pada 22 November 2007, Parlemen menyetujui Bayar sebagai Perdana Menteri Mongolia dengan 67 suara setuju (97,1%) dan dua melawan.

He began his career as Prime Minister with verbal attacks (speech at his appointment) against Tsakhiagiin Elbegdorj and the nationalisation of the 15% share of Mongolian companies in the Tavantolgoi mine, making it a 100% public venture, thus inducing enthusiasm of Russian companies in the large coal deposit. Most of the members of a three-party coalition government, led by Bayar and dominated by the MPRP, were approved by Parliament on December 5, 2007; the government included Bayar's predecessor, Miyeegombyn Enkhbold, as Deputy Prime Minister. This government was planned to serve until the June 2008 parliamentary election. On September 11, 2008, following the MPRP's victory in the June parliamentary election, S. Bayar was elected as the new Prime Minister of a coalition government between the MPRP and DP. Under his leadership, the Mongolian Government finally signed an investment agreement to mine the Oyu Tolgoi copper deposit.
