Manual Santos，the ruling Socialist Party of National Unity candidate，backed by President Alvaro Uribe，was elected Colombia’s 59th president and took office in August 2010. In the Congressional election the center-right alliance succeeded in increasing its seats. The Santos government listed economic and social development as top priorities and implemented a new policy agenda labeled “Democratic Prosperity”，regarding agriculture，infrastructure，housing，mining and energy as the five engines of economic growth. Columbia attempted to resolve the intensity invoked by the Colombian-US Military Cooperation Agreement and had restored the diplomatic ties with Venezuela and Ecuador. The Sino-Colombian relations continued to develop based on the increase of bilateral trade.
