Japanese researchers hope to restore coral from Saudi-made structures

  • Coral skeletons made for Saudi Pavilion at Japan expo last year
  • Results of Japanese study to be revealed at Riyadh Expo 2030

TOKYO: Japanese universities are seeking to restore coral reefs and marine ecosystems after receiving artificial structures that Saudi Arabia made and showcased at last year’s Osaka-Kansai Expo.

The coral skeletons were donated to the University of the Ryukyus in Okinawa and Kansai University in Osaka Prefecture, Kyodo News reported at the weekend.

The structures are made from calcium carbonate, a material on which corals are believed to grow more easily compared to artificial alternatives such as concrete or metal.

The skeletal structures were created using 3-D printers, with one piece produced a day during the expo, and displayed across an entire wall in the Saudi Arabia Pavilion, which had an area focusing on sustainable marine environments.

Coral reefs serve as habitats for much marine life, but over 40 percent of the world’s 892 species face possible extinction, according to the International Union for Conservation of Nature.

The University of the Ryukyus, which received about 150 of the artificial coral skeletons, will place them in waters off the eastern coast of Okinawa’s main island and then examine their impact on the ecosystem.

Kansai University has placed theirs in the sea around Kagoshima Prefecture’s Yoron Island to observe their growth after transplanting coral polyps onto the structures.

The results of the research are expected to be revealed at the Riyadh Expo in 2030.

“I had never imagined that Japan and Saudi Arabia would cooperate on coral research,” said Masato Ueda, a professor specializing in regenerative medicine at Kansai University.

Ueda said he wants to demonstrate to children that “humanity is attempting to restore the environment.”

Threat to Kingdom’s security is ‘red line’ that will be ‘addressed and neutralized,’ Saudi envoy says

  • Abdulaziz Alwasil tells UN Security Council the situation in southern Yemen is ‘a just cause with social and historic dimensions’ that can only be resolved through dialogue
  • Recent military activity in the south was unilateral, resulting in an escalation that harms the interests of Yemeni people and undermines efforts to address issues in the south, he said

NEW YORK CITY: Any attempt to threaten Saudi Arabia’s national security is a “red line” and will be met with decisive action, the Kingdom’s ambassador to the UN told the Security Council on Wednesday.

Speaking during a meeting of the council to discuss Yemen, Abdulaziz Alwasil said the situation in the south of the country is “a just cause with social and historic dimensions” that can only be resolved through dialogue.

“We stress that any attempt to threaten our national security is a red line, and we will not hesitate to take the necessary actions and steps to address it and neutralize it,” he added.

Alwasil reaffirmed Saudi Arabia’s support for Yemeni President Rashad Al-Alimi, the Presidential Leadership Council, and the Yemeni government in their efforts to achieve security, stability, development and peace while preserving national unity.

He said military activity by Southern Transitional Council forces in Hadramout and Al-Mahra on Dec. 2, 2025, was unilateral, did not have the approval of the Presidential Leadership Council, and was not carried out in coordination with the Coalition to Restore Legitimacy in Yemen.

It had resulted in an unjustified escalation that harmed the interests of the Yemeni people, undermined efforts to address the issues in the south, and ran counter to the coalition’s objectives, Alwasil added.

The Kingdom, working with its coalition partners, the Presidential Leadership Council and the Yemeni government, had moved to contain the situation by dispatching a military force to coordinate arrangements with the Southern Transitional Council in Aden, he said.

The aim was to ensure the return of the southern council’s forces to their previous positions outside of Hadramout and Al-Mahra, and the handover of camps to legitimate government forces and local authorities in line with agreed procedures, Alwasil added.

He expressed regret over the military operations that took place in Hadramout and Al-Mahra, close to Saudi Arabia’s southern border, which he said posed a direct threat to the Kingdom’s national security, as well as the security of Yemen and regional stability. Such steps were extremely dangerous, he added, and contradicted the principles on which the Coalition to Restore Legitimacy in Yemen had been founded.

Alwasil welcomed a prisoner and detainee exchange agreement signed in Muscat on Dec. 23, which he described as an important humanitarian measure to alleviate suffering and build confidence.

He praised Oman for hosting and sponsoring the consultations and supporting negotiations, and commended the efforts of UN’s special envoy for Yemen, Hans Grundberg, the International Committee of the Red Cross and all others that has played a part.

Regarding the political efforts to resolve the crisis, Alwasil said Saudi Arabia welcomed President Al-Alimi’s call for an inclusive conference in Riyadh to bring together all stakeholders to discuss just solutions to the situation in southern Yemen.

Preparations for the conference have begun, he added, in cooperation with the Yemeni government and southern representatives, reflecting the close ties between the two countries and their shared interests in stabilizing Yemen.

He urged all southern stakeholders to participate actively and constructively in the talks, to help find comprehensive and just solutions that meet the legitimate aspirations of the people of southern Yemen.

Alwasil called on all Yemeni forces and stakeholders to cooperate and intensify their efforts to reach a lasting political settlement that would ensure security and stability.

He described the southern issue as “a just cause with social and historic dimensions,” adding that “the only way to address it is through dialogue that leads to a comprehensive political solution” based on nationally and internationally agreed terms of reference.
