((Xinhua)) - Xi Jinping was unanimously elected Chinese president on Friday at the ongoing session of China's national legislature, leading the country of 1.4 billion people onto a new journey toward modernisation.

He was also elected chairman of the Central Military Commission (CMC) of the People's Republic of China (PRC) by a unanimous vote.

A total of 2,952 deputies were present at the third plenary meeting of the first session of the 14th National People's Congress (NPC) on Friday morning, to exercise their constitutional right to elect China's state leadership.

The voting was anonymous.

Thunderous applause broke out across the Great Hall of the People when the results of the elections were pronounced.

Xi, donning a dark suit with a burgundy tie, rose from his seat and bowed to the lawmakers.

Born in 1953, Xi joined the Communist Party of China (CPC) in January 1974, and became the Party branch secretary of the Liangjiahe Brigade in rural Shaanxi Province, later the same year.

He then embarked on a journey across China that saw him work in different provinces and municipalities and rise from the grassroots level to the helm of the Party and the state.

Xi was first elected general secretary of the CPC Central Committee and named chairman of the CPC Central Military Commission in November 2012. He was elected Chinese president and CMC chairman of the PRC in March 2013.

The solemnity of Friday's assembly was underscored by a ceremony of Xi and other newly elected state leaders pledging allegiance to China's Constitution.

After a chorus of the national anthem was sung by all present, Xi placed his left hand on a copy of the Constitution and held up his right fist.

"I pledge my allegiance to the Constitution of the PRC to safeguard the Constitution's authority, and fulfill my legal obligations, be loyal to the country and the people, be committed and honest in my duty, accept the people's supervision, and work for a great modern socialist country that is prosperous, strong, democratic, culturally advanced, harmonious, and beautiful," Xi said.

Under Xi's leadership, the world's second-largest economy is marching on a model of modernization that has not been seen before.

In the past decade, China's GDP has grown to 121 trillion yuan (about 17.37 trillion U.S. dollars) from 53.9 trillion yuan in 2012.

The Chinese economy has come to account for over 18 percent of the world economy over the past 10 years, and its contribution to the world's economic growth has averaged over 30 percent.

The country has eradicated absolute poverty and built the largest education, social security, and healthcare systems in the world.

The average life expectancy of the Chinese has increased from 74.8 to 78.2 years over the past decade, and there have been historic, transformative, and comprehensive changes in ecological and environmental protection.

China has also joined the ranks of the world's innovators, and achieved an overwhelming victory and fully consolidated the gains in the fight against corruption.

Observers believe Friday's elections will inject greater certainty into China's modernisation drive.
