Patiño :
Since 2008, China has maintained a standing People's Liberation Army Navy (PLAN) task force in the Gulf of Aden as an anti-piracy measure in response to piracy off the coast of Somalia. The task force was initially authorized to escort only Chinese ships and ships carrying humanitarian supplies to Somalia; this was later expanded to accept commercial ships from other countries. Escorting Chinese ships in the Red Sea may have begun in January 2024 in response to the Red Sea crisis.
The task force is China's first sustained "far seas" military presence. It provides the PLAN with "invaluable" operational experience, the benefits of which are spread by rotating units from all fleets into the task force.

## Background
### Impact of piracy

In the 2000s, China developed greater interest and capability to protect its global interests.
Chinese discussions through 2012 identified the strategic importance of securing maritime trade routes. Shipping contributed to China's financial and energy security. 90% of China's international trade in goods was moved by ship. It became a net oil importer in 1993, and of natural gas in 2007. By 2012, 80% of imported oil arrived by sea. Reliable routes affected oil prices, which affected the stability of the United States dollar, and which in turn affected the value of Chinese investments in the United States (US) and US capacity to buy Chinese products.
By 2009, views expressed by Chinese analysts included identifying piracy as a threat to national interests and that the state had a responsibility to protect Chinese shipping.
Global piracy increased every year from 2005 to 2010. China's response to piracy was uncoordinated and informal. The Ministry of Transport (MoT) responded to pirated ships through intermediaries, but this was "not very effective." Anti-pirate tactics for civilian ships recommended by MoT were also inadequate. By 2008, there was domestic support for comprehensive protective measures. By October, Chinese shipping companies, MoT, and the Ministry of Foreign Affairs (MoFA) supported deploying naval escorts. That year from January to November, 83 of 1265 Chinese ships were attacked with several being pirated.

### Legal considerations

Intervention would require exercising force inside the exclusive economic zone of another country beyond China's periphery. This novel scenario for Chinese foreign policy and law, combined with internal debate over the legality of intervention in terms of domestic and international law, delayed action. Three United Nations Security Council (UNSC) resolutions in 2008 authorizing intervention in Somali waters may have provided China with part of the legal foundation to intervene. Another part was securing an invitation from the Transitional Federal Government of Somalia (TFG) to avoid appearances of subverting sovereignty.

## Planning and preparation

International and domestic pressure led the PLAN, the MoT, and the MoFA to developed a policy framework for the mission with "unusual alacrity" in late-2008.
The PLA began feasibility studies in May 2008; a task force may have been seen as an opportunity to test the navy's newest equipment. The PLAN publicly announced its support in November, and the Central Military Commission (China) (CMC) approved the navy's plan shortly afterward.
China "worked frantically" to secure an agreement from the Somali TFG. In a late-November interview with the Global Times, Mohammed Ahmed Awil, the TFG's ambassador to China, reported that the TFG had sent an invitation for Chinese warships and was awaiting a response. In mid-December, Awil and Ali Jangali, the Somali Minister of Foreign Affairs reiterated the TFG's support for a Chinese naval task force.
On 20 December 2008, China announced it would deploy a naval task force. This followed the adoption of United Nations Security Council Resolution 1851, which extended the area of operations of UN authorized anti-piracy operations to include the Somali coast.

## International cooperation

In late-November 2024, Wolfgang E. Nolting, the commander of the German Navy, met Liang Guanglie, China's Minister of National Defense, in Beijing and discussed military aspects of China–Germany relations. Nolting hoped improved cooperation would extend to anti-piracy efforts.
China's escort mission is organizationally independent from other coalition forces. In 2008, China may have perceived international piracy law as being too immature to provide a framework. Furthermore, the existing coalition forces - the United States' Combined Maritime Forces, NATO's Operation Ocean Shield, and the European Union's Operation Atalanta - were not UN-led, and close integration may have allowed partners to gather intelligence on Chinese capabilities. Integration may also have required installation of foreign software or hardware which may not have been possible or desirable for security reasons.
China participates in Shared Awareness and Deconfliction (SHADE) which provides a high-level discussion forum for coordinating counter-piracy forces. SHADE does not exercise control over participating forces.

## Organization and mission scope

The mission is jointly managed by the PLAN, the MoT, and the MoFA. The MoT participates in coordinating Chinese anti-piracy efforts with other countries and media relations.
The naval forces are controlled by PLAN headquarters instead of the Joint Staff Department, which nominally has control over operations beyond China's periphery. A task force is deployed by a PLAN fleet and typically include two warships, a supply ship, and approximately 800-personnel. The formations deploy for four to six months. It takes about two weeks to sail from China to Somalia.
Rules of engagement are restrictive to avoid capturing pirates and the need to prosecute them. Euspected pirates are advised to disengage through visual, verbal, and live-fire warnings before escalating the engagement; the main tactic is to deter, drive away or disarm attacks. China's justice system lacks mechanisms to prosecute piracy, and it is also reluctant to try criminals captured in foreign countries in domestic courts. China is also sensitive to the lack of an internationally-agreed upon process for dealing with captured pirates.
Nearby ports used for replenishment include Aden, Djibouti City and Salalah. Djibouti was used as a forward repair base in August 2009; China's first overseas military base opened in Djibouti in August 2017.
The initial mission was the protection of UN World Food Programme aid to Somilia and Chinese shipping. This was expanded to foreign ships; foreing requests are handled through the MoT. In 2024, escorts may have started for Chinese ships in the Red Sea.

## Events

The first task force deployed from Sanya on 26 December 2008.
In March 2011, the frigate Xuzhou from the seventh task force escorted a civilian ship transporting Chinese evacuated from the Libyan civil war. This was the PLAN's first noncombatant evacuation operation overseas.
By the end of 2012, the task forces had escorted over 5000 ships.
