People from both sides of the Taiwan Strait said that no separatist forces can erase the shared history and national identity that bind people across the Strait, as the 80th anniversary of Taiwan's restoration to China was commemorated in Beijing.

A grand gathering celebrating the anniversary was held in Beijing on Saturday. It marked the first Commemoration Day of Taiwan's Restoration, following an official designation on Friday by the Standing Committee of the 14th National People's Congress, China's top legislature.

Wang Huning, chairman of the National Committee of the Chinese People's Political Consultative Conference, addressed the event, calling on compatriots on both sides of the Strait to work together to advance national reunification and to firmly oppose all forms of "Taiwan independence" separatist activities.

Wang stressed that the establishment of the commemoration day demonstrated the unwavering commitment of all Chinese people to uphold the one-China principle and safeguard national sovereignty and territorial integrity.

After the event, several guests from Taiwan said the commemoration had strengthened their confidence in the nation's eventual reunification.

Justin Lin Yifu, a Taiwan-born economist and professor at Peking University, said that Taiwan's restoration to China and the victory in the Chinese People's War of Resistance Against Japanese Aggression (1931-45) should be remembered by all Chinese people.

"The course of history will not be altered by the obstruction of a small handful of people," he said, adding that the commemoration day strengthens pride in being Chinese.

Wu Jung-yuan, chairperson of Taiwan's Labor Party, said the establishment of the commemoration day demonstrated to the world that commemorating Taiwan's restoration is the heartfelt, shared wish of compatriots on both sides of the Strait.

"Our shared bonds and memories cannot be severed by any external forces or separatists," he emphasized.

Wu added that the decision provided strong legal and political support for all patriotic forces committed to advancing the cause of national reunification.

On Oct 25, 1945, the ceremony to accept Japan's surrender in the Taiwan province of the China war theater of the Allied powers was held in Taipei. From that moment, Taiwan and the Penghu Islands were restored to China's sovereign jurisdiction.

Shaw Kai-ping, honorary president of the association for relatives of patriots in Taiwan who fought against Japanese aggression, said it was a great honor for Oct 25 to be established as a national commemoration day. Shaw's father and grandfather both took part in the resistance against Japanese occupation.

"This decision shows that the motherland has not forgotten the people of Taiwan, and that reunification is destined to be achieved," Shaw said.

Chi Chia-lin, honorary chairman of the Reunification Alliance Party in Taiwan, said he had long awaited the establishment of the commemoration day. "As the historical truth comes to light, more and more people are gaining a clearer understanding of what really happened," Chi said.

The Taiwan Work Office of the Communist Party of China Central Committee and the Taiwan Affairs Office of the State Council hosted a reception in Beijing on Saturday, attended by guests from both Taiwan and the mainland who had participated in the earlier gathering.

Song Tao, head of both offices, said at the reception that establishing the commemoration day on the occasion of the 80th anniversary of Taiwan's restoration fully reflects the will of the people and the resolve of the nation.

"We are confident in advancing the great cause of national reunification and enhancing the well-being of our Taiwan compatriots," Song said.

Chi Hsing, publisher of The Observer magazine in Taiwan, said the decision reflects the shared aspirations of the vast majority of Taiwan compatriots.

"It will carry forward the patriotic tradition, reaffirm that both sides of the Strait belong to one China, and inspire pride in being Chinese," she said.

Ji Bin, vice-chairman of the All-China Federation of Taiwan Compatriots, said the restoration of Taiwan is solid evidence of the Chinese government's resumption of sovereignty over Taiwan and a crucial link in the historical and legal chain of Taiwan being part of China.

"No matter how the Democratic Progressive Party and its politicians distort the truth of the war of resistance against Japanese aggression, deny the achievements of the war victory, downplay or deny the historical significance of Taiwan's restoration, and collude with external forces to promote the fallacy of 'Taiwan's undetermined status', they cannot distort or undermine the historical and legal fact that Taiwan belongs to China," Ji said.

In Taipei, the memorial association of the Chinese war of resistance against Japanese aggression in Taiwan and the Chinese Kuomintang party jointly held a celebration on Saturday marking the anniversary of Taiwan's restoration.

Overseas Chinese from both sides of the Strait also celebrated the commemoration day in various forms. Chinese embassies in countries including the United States, Japan, Brazil and Indonesia held symposiums marking the 80th anniversary of Taiwan's restoration on the day of commemoration.

In New York City, hundreds of Chinese compatriots from both sides of the Strait gathered in the Flushing neighborhood of Queens borough on Friday to celebrate the anniversary.
