Foreign leaders including Russian President Vladimir Putin sent messages to Xi Jinping on Saturday to congratulate him on his election as China's president.
Cameroonian President Paul Biya voiced his hope for Xi's every success in fulfilling the noble mission, and said he would like to work with Xi in strengthening the unique friendship and cooperation between Cameroon and China.
Xi vowed to fully and accurately implement the principle of "one country, two systems", Hong Kong people governing Hong Kong and Macao people governing Macao with a high degree of autonomy.
Xi also expressed gratitude to the NPC deputies and the whole nation for electing him president. He pledged to be loyal to the country and the people, spare no effort to fulfill his duties, be diligent at work, accept supervision from the people and never let the people down.
Only by adhering to and developing socialism with Chinese characteristics can the Chinese nation realize its great rejuvenation, Xi said.
"We will devote more energy and take more concrete measures in ensuring and improving people's living standards, strengthening and developing new approaches to social governance, resolutely winning the battle against poverty, promoting social fairness and justice and making steady progress in ensuring people's access to child care, education, employment, medical services, elderly care, housing and social assistance," Xi said.
