China's economy has shown remarkable resilience and vitality over the past year amid rising global uncertainties, Liu Jieyi, spokesman for the fourth session of the 14th National Committee of the Chinese People's Political Consultative Conference, said.

"China's gross domestic product surpassed 140 trillion yuan ($20.4 trillion) last year, marking a new milestone," Liu said, adding that its growth rate remained among the highest of major economies globally.

Liu made the remarks at the nation's top political advisory body's news conference on Tuesday, one day ahead of its annual session.

The past year also saw deeper integration of technology and industry, fueling a surge of innovation, with new quality productive forces gaining momentum, Liu said.

Highlighting the robust dynamism of China's vast market, Liu noted that during the latest Spring Festival holiday, the longest on record at nine days, domestic tourism spending surged to over 803.4 billion yuan, up by 126.4 billion yuan year-on-year.

"While the Chinese economy still faces certain deep-seated issues and emerging challenges," Liu added, "the nation's solid foundation, multifaceted advantages, robust resilience, and immense potential remain intact."

"The long-term positive trajectory of the economy has not changed," Liu added.

Meanwhile, China's top political advisory body has pledged to offer consistent wisdom and strength in support of building a unified national market, promoting the high-quality development of the private sector, and fostering emerging and future industries, according to Liu.
