> Bilateral agreements that grant foreign forces the right to base, transit, or pre-position on another state's territory, now central to US-China competition across the Indo-Pacific.

## What it is

A basing rights agreement is a bilateral treaty or executive agreement under which one state grants another's military forces the right to operate from, transit through, or pre-position equipment on its territory. In practice, three instruments work together: the base rights agreement (specifying which facilities may be used and on what terms), a status of forces agreement (SOFA, governing jurisdiction over visiting personnel and property), and a visiting forces agreement (VFA) for rotational rather than permanent deployments. SOFAs typically exempt visiting personnel from host-nation criminal jurisdiction, the most politically sensitive provision, and establish which state pays for damages and environmental remediation. As of mid-2024, the US Department of Defense manages or uses at least 128 overseas bases across 51 countries, with roughly 750 sites counted under broader methodologies that include jointly operated and access-only facilities.

## History

Basing rights became a distinct diplomatic instrument after World War II, when the United States and the Soviet Union competed to convert wartime logistics networks into peacetime presence. The postwar settlement left US forces in Japan (1951 security treaty), South Korea (after the 1953 armistice), and across NATO Europe. After the September 2001 attacks, a rapid wave of deals opened facilities in Kyrgyzstan, Uzbekistan, and Djibouti. Qatar's Al Udeid Air Base, expanded after 2001, now hosts the US Central Command's forward headquarters. By the 2010s the US had pivoted from large permanent garrisons toward "places, not bases," a posture of rotational access to allied facilities that minimises political exposure in host countries. China followed a parallel track, opening its first overseas military logistics base in Djibouti in 2017, its only formally acknowledged one as of early 2026, while pursuing port-access arrangements through Belt and Road infrastructure agreements.

## Current state

As of mid-2026, competition for basing access is sharpest in three theatres. In the Indo-Pacific, the US has expanded rotational access in Australia, the Philippines (under the Enhanced Defense Cooperation Agreement), and Papua New Guinea. The [Nakamal Agreement](/zh/n/australia-vanuatu-nakamal-jun29), signed June 29, 2026, bars Vanuatu from hosting any foreign military base or infrastructure, a provision Australia secured with A$500 million (roughly US$345 million) in development commitments. The [Chinese government's response](/zh/n/china-vanuatu-australia-reaction-jun30) framed the deal as targeting Beijing's legitimate interests in the region. In Europe, Russia's February 2022 invasion of Ukraine triggered new NATO basing arrangements: the US reactivated Iceland's Keflavik Naval Air Station, expanded the Polish garrison, and signed expanded access agreements following Finland's and Sweden's NATO accessions. In Africa, France's contracting Sahel garrison network is opening space for competing US, Chinese, Russian, and Gulf-state offers.

## Relationships

Basing rights sit at the intersection of sovereignty, deterrence, and economic leverage. Access to foreign ports and airfields compresses logistics timelines, often a decisive variable in a fast-moving crisis. For small states, hosting foreign forces provides security guarantees, economic transfers (base rents, construction contracts, local employment), and diplomatic weight, at the cost of sovereignty constraints and domestic political blowback. The criminal jurisdiction provisions of SOFAs attract recurring friction, notably in Okinawa, Japan and the Philippines, where incidents involving visiting US forces have sparked repeated protests and treaty renegotiations. The shift toward dual-use civilian infrastructure, ports, airfields, and fibre cables funded through development aid, has blurred the line between basing rights and economic statecraft, and the Nakamal Agreement illustrates how a security pact and an infrastructure-financing package can be a single instrument.

## What to watch

- Whether the Philippines renews or restricts US access under the Enhanced Defense Cooperation Agreement as domestic political pressures continue.
- Whether China converts port-access arrangements at Cambodia's Ream Naval Base into a formally acknowledged overseas military base.
- How the US Congress appropriates for the Pacific Deterrence Initiative, the primary funding mechanism for access infrastructure in partner nations.
- Whether any Pacific Island state signs a formal basing agreement with China, crossing the red line that the Nakamal Agreement was designed to draw for the region.
