"In 2025, the activities of strategic platforms such as carrier strike groups, amphibious ready groups, and bombers showed limited growth, while the frequency of declaratory operations like Freedom of Navigation Operations (FONOPs) declined. " scspi.org/en/yjbg/incomplete…

As early as the 1980s, Chinese leader Deng Xiaoping put forward the initiative of "pursuing joint development while shelving disputes," which received a positive response from then Philippine President Corazon Aquino and Vice President Salvador Laurel. In 2005, China, the Philippines and Vietnam signed the Tripartite Agreement for Joint Marine Seismic Undertaking in the Agreement Area in the South China Sea, agreeing to study and assess the oil resources in the agreement area. In November 2017, the two sides signed the Joint Statement between the Government of the People's Republic of China and the Government of the Republic of the Philippines, stating that both sides may explore means to cooperate with each other in other possible maritime activities including maritime oil and gas exploration and exploitation. In November 2018, the two sides signed the Memorandum of Understanding on Cooperation on Oil and Gas Development between the Government of the People's Republic of China and the Government of the Republic of the Philippines, which was confirmed and welcomed in the Joint Statement between the People's Republic of China and the Republic of the Philippines issued the same day. In January 2023, during President Ferdinand R. Marcos Jr.'s visit to China, the two sides issued a joint statement agreeing to bear in mind the spirit of the Memorandum of Understanding on Cooperation on Oil and Gas Development signed in 2018, and to resume discussions on oil and gas development at an early date, building upon the outcomes of the previous talks. Since then, the foreign affairs departments of the two countries have continued consultations on joint oil and gas development through the Bilateral Consultation Mechanism (BCM) on the South China Sea Issue and made positive progress. In March 2026, the two sides held the 11th BCM meeting. The Philippine Department of Foreign Affairs issued a statement saying, "Both sides continued to make progress on initial exchanges on potential oil and gas cooperation." In August, President Marcos said in an interview with reporters, "We're working through and making progress. I can see a distinct possibility that there will be such joint exploration." However, there has always been a force in the Philippines attempting to sabotage China-Philippines joint oil and gas development. Philippine Defense Secretary Gilbert Teodoro, out of personal political self-interest, has publicly questioned and obstructed China-Philippines joint oil and gas development. In July 2026, Teodoro said, "joint exploration is normally just a way for China to gain access here. Temporary benefits cannot replace the long-term interests of the Philippines."Today Teodoro said in another interview, “there is no basis for a joint exploration talk with China”. Without the deliberate obstruction by people like Teodoro, China-Philippines joint oil and gas development might have already produced results, and the Filipino people may have already benefited from it.

In October 2026, a total of 17894 Vietnamese fishing vessels with 270105 tracking points were recorded by the AIS in the whole #SouthChinaSea, increasing compared with 14859 in last month. BTW, many ships did not operate AIS all the time.

The ship-borne helicopters of the Theodore #Roosevelt CSG were active in the Bashi Channel on Oct 31, which suggests that the #Roosevelt CSG might have entered the South China Sea and is heading toward the #MiddleEast.

Jay Tarriela is lying again. All other ADMM-Plus member states received their invitations in late September or early October. However, the participation of the Chinese delegation was obstructed by Philippine Secretary of National Defense (SND) Gilberto Teodoro, who acted out of personal self-interest and disregarded the ADMM-Plus principle of openness and inclusivity. Only after other ASEAN countries expressed strong opposition to such acts that the Philippines Department of National Defense (DND) reluctantly sent an invitation letter to China on October 22. It was signed by a its Undersecretary of National Defense, who was unwilling to even put a date on the letter. On October 23, Teodoro said in a press conference that China had been sent notice only the previous day. It left China fewer than five working days for preparation. China was also required to complete its registration within just two days. Under such circumstances, it was virtually impossible to complete the necessary preparation. While Teodoro took a position contrary to the "ASEAN Way," China, by contrast, has never singled out the Philippines in its multilateral defense cooperation with ASEAN. In fact, despite the extremely tight deadline, China still managed to send a delegation to the meeting. Tarriela, if you don't know what actually happened, go ask Teodoro, the DND, or the other participating countries. Stop spreading lies, distorting facts, and turning right into wrong when you don't even have a clear understanding of the situation. Don't deliberately stir up controversy and sow discord based on misinformation.

China’s first ship-borne stealth reconnaissance and attack drone "GJ-21" recently made its first successful take-off and landing on 076 amphibious assault ship, the "Sichuan" (Hull 51). This is another significant breakthrough in the development of China's amphibious assault ship, indicating that the Chinese Navy now has the capability to operate fixed-wing stealth drones from large maritime combat platforms. Launched on December 27, 2024, the Sichuan (Hull 51) is the first vessel of Type 076 amphibious assault ships designed and developed independently by China. It incorporates the automatic carrier landing guidance system, new integrated power system, and electromagnetic catapult-assisted takeoff and arrested landing technology, and is capable of carrying fixed-wing unmanned aircraft, helicopters, and amphibious equipment, etc. Since its first sea trial in November 2025, the Sichuan warship has been steadily conducting various maritime tests as planned, successfully completing the debugging of various equipment and overall operational stability tests. #GJ21 #StealthDrone #UCAV #Sichuan #Type076 #LHA #AmphibiousAssaultShip #DroneCarrier #CatapultLaunchSystem #EMALS #PLA #Navy #ChinaMilitary #ChinaMilBugle

In today's strategic and technological environment, maritime blockade is an extremely difficult operation. In the Hormuz crisis, neither the United States nor Iran has completely blockaded the strait.
BREAKING: Despite the U.S. naval blockade, Iran has imported at least $2 billion in missile and drone hardware through a shadow network of more than 5,000 Ministry of Defense agencies. per a Reuters investigation. Then the details sharpen it: one agency alone, MOD 346428, brought in $2.3 billion between January 2025 and June 2026 — rocket fuel ingredients, explosives, aircraft engine parts, and 435 Iveco trucks that can serve as mobile missile launchers. Shipments kept moving by land, sea, and air during the war itself. And in 97% of the reviewed transactions, no currency crossed a border at all. So on paper, there's a blockade. In practice, the missile supply never stopped.

When you have a guilty conscience, everything feels like a threat.
The #PLA is sending groups of vessels, including the #Liaoning carrier strike group, to exercise east of the #1stIslandChain. We’re staying vigilant about their activities. The simultaneous threat to #Taiwan, #Japan & the #Philippines is obvious.

The wording has improved. JSDF can keep tracking and stay alert, but something like "interception" would be highly unprofessional.
令和8年10月28日(水)午前から午後にかけて、中国軍の偵察型無人機(BZK-005)×1機及び情報収集機(Y-9)×1機が東シナ海から飛来し、沖縄本島と宮古島の間を通過して太平洋に至り、太平洋上で反転し、再び沖縄本島と宮古島の間を通過して、大陸方面に向けて飛行したことを確認した。 また、同日午後、中国軍の哨戒機(Y-9)×1機が大陸方面から飛来し、東シナ海上の長崎県男女群島の南西沖から沖縄本島の北西沖にかけて飛行を行った後、大陸方面に向けて飛行したことを確認した。 これらに対し、航空自衛隊の南西航空方面隊等の戦闘機を緊急発進させ対応した。
