BEIJING -- When To Lam made his first visit to China as Vietnam's top leader in August last year, he started the trip not in Beijing but in the southern metropolis of Guangzhou -- a special arrangement Chinese President Xi Jinping later hailed as "quite meaningful."

It was in Guangzhou, a century earlier, that Ho Chi Minh, the late Vietnamese leader, began his revolutionary activities in China, a period of history Xi described as "a shared red memory" between the two countries' ruling parties.

Xi will soon travel to Vietnam for a fourth state visit as general secretary of the Communist Party of China (CPC) Central Committee and Chinese president. The trip coincides with the 75th anniversary of diplomatic ties between China and Vietnam, two socialist neighbors that have forged an enduring bond as "comrades and brothers."

Behind the metaphors lies more than a diplomatic formality. Xi sees the enduring China-Vietnam friendship as a living cause to be carried forward. His upcoming visit offers a moment to draw inspiration from the storied past to chart the future course of bilateral relations.

During a state visit to Vietnam in 2017, Xi brought along a special national gift -- 19 issues of The People's Daily, the official newspaper of the CPC Central Committee.

Among the newspapers were 16 yellowed copies carrying news reports on Ho Chi Minh. "These newspapers date back to Chairman Ho's visit to China in 1955. It took us quite some effort to find them," Xi explained.

One notable edition, dated June 26, 1955, featured a full-column front-page photograph of Ho alongside Mao Zedong, Zhou Enlai and other first-generation CPC leaders.

Ho, who founded the Communist Party of Vietnam (CPV) in Hong Kong and led Vietnam's liberation, forged close personal ties with CPC leaders during his 12 years of revolutionary activities in China. "He was like a brother for Chairman Mao Zedong, Premier Zhou Enlai and other Chinese leaders," Xi wrote in a signed article published by the major Vietnamese newspaper Nhan Dan (People) ahead of the 2017 visit.

Xi holds dear the indelible contributions these great forerunners made to fostering the China-Vietnam friendship. During his first state visit to Vietnam in 2015, in a speech to Vietnam's National Assembly, Xi quoted Ho's own words: "China and Vietnam enjoy comradely and brotherly friendship."

Xi once shared his personal regard for Chairman Ho while speaking with Vietnamese youth. "We call him 'Uncle Ho'," Xi said. He noted that in the hearts of the Chinese people of his generation, Chairman Ho is remembered as the best friend of the Chinese people.

Back in 2011, Xi, then Chinese vice-president, visited Ho's former residence to learn more about his life. Before his departure, Xi left an inscription: "The great man's spirit shall be honored for millennia, and the China-Vietnam friendship shall endure through the ages."

Six years later, during the 2017 state visit, Xi once again toured Chairman Ho's former residence. At a pond near the Ban Sao Nak, the wooden house where Ho once lived and worked, Xi learned to clap his hands before feeding fish, the same practice Ho once used to draw fish closer.

While there, reflecting on bilateral ties, Xi said, "We should learn from Chairman Mao, Premier Zhou and Chairman Ho, and carry forward and develop China-Vietnam friendship for the benefit of both our peoples."
