Tacoma’s International Infrastructure Is Older Than Most People Realize
Tacoma’s first sister city relationship — with Kitakyushu, Japan — was established in 1959, three years after President Eisenhower created the Sister Cities International program. That’s 67 years of institutional relationship-building with one of Japan’s major industrial port cities. And it wasn’t an accident: Kitakyushu and Tacoma are both working port cities with steel, shipping, and manufacturing in their DNA.
Today, Tacoma maintains 14 official Sister City relationships, plus four Friendship Cities and six Provisional Friendship Cities. The full list, with establishment dates:
Tacoma’s 14 Sister Cities
1959 — Kitakyushu, Japan. 1978 — Gunsan, South Korea. 1986 — Aalesund, Norway. 1992 — Vladivostok, Russia. 1994 — Fuzhou, China. 1994 — Davao City, Philippines. 2000 — Taichung, Taiwan. 2000 — Cienfuegos, Cuba. 2008 — El Jadida, Morocco. 2012 — Biot, France. 2016 — Boca Del Rio, Mexico. 2017 — Brovary, Ukraine. 2025 — Split, Croatia. 2025 — Garden Route Municipality, South Africa (elevated from George, originally established 1997).
The geography is deliberate. These cities ring the Pacific Rim, span key European trade corridors, and connect to African and Latin American markets. Tacoma limits Sister City partnerships to one city per country, which means each relationship carries the weight of representing an entire bilateral connection.
The World Trade Center Tacoma: 47 Years of Trade Infrastructure
The World Trade Center Tacoma (WTCT) has operated since 1979, making it one of the longest-running trade facilitation organizations in the Pacific Northwest. The WTCT is part of the global World Trade Centers Association network, which spans nearly 100 countries, 335 cities, and 1.2 million member companies.
What makes the WTCT distinctive is its structure: it’s managed by the Tacoma-Pierce County Chamber of Commerce with its own board of directors, and it’s the only full-service trade center in the Pacific Northwest. That means it provides the complete stack — trade missions, market research, buyer-seller matchmaking, export assistance, and cultural bridge-building — not just a membership directory.
According to the Port of Tacoma, the WTCT has helped thousands of local businesses succeed in international markets since its founding, organizing periodic trade missions to international markets to assist delegates in meeting buyers and key contacts.
The Numbers: $76 Billion and 3.3 Million TEUs
The Northwest Seaport Alliance — the joint operating entity between the ports of Tacoma and Seattle — handled 3,340,733 TEUs in 2024, up 12.3% over 2023. Full imports increased 19.6% and full exports grew 8.1%. The Alliance facilitated nearly $76 billion of waterborne trade with 176 trading partners globally.
Through mid-2025, volumes continued strong: Q1 2025 TEU volumes were up 19% year-over-year. However, tariff impacts began weighing on volumes by mid-year, with full international imports declining 27.3% in June 2025 versus June 2024.
Tacoma marine cargo and real estate operations support more than 29,000 jobs in the region, according to Make It Tacoma. International exports from the Tacoma region total approximately $10 billion annually.
What These Relationships Actually Produce
Sister city relationships get dismissed as ceremonial. Some are. But Tacoma’s are anchored to real economic activity because the city’s identity is built on trade. When the mayor’s office sends a delegation to Kitakyushu or Fuzhou, they’re not just exchanging plaques — they’re opening doors for businesses that need introductions in markets where relationships precede transactions.
The Washington Export Resource Center lists the WTCT as a primary resource for export assistance, connecting Tacoma-area businesses with the state’s broader trade support infrastructure. The WTCT’s trade missions have historically focused on key markets aligned with the sister city roster — Japan, South Korea, Taiwan, China, and the Philippines.
The two newest additions — Split, Croatia and the Garden Route Municipality in South Africa, both added in 2025 — signal an expansion beyond Pacific Rim markets into European and African corridors. Tacoma is also building provisional relationships with Mannheim, Germany and multiple Chinese cities (Ningbo, Putuo District/Shanghai, Nanshan District/Shenzhen), suggesting the next wave of formal sister city designations will deepen the China trade relationship.
The Operator’s Perspective
I live in a port city. The cranes at the Port of Tacoma are visible from my neighborhood. The container trucks run on the roads I drive. This isn’t abstract — the $76 billion in waterborne trade that moves through the Seaport Alliance affects commercial real estate, warehouse demand, trucking employment, and the tax base that funds every city service.
For local operators, the sister city and WTC infrastructure represents a built-in international business development platform that most mid-sized cities simply don’t have. If you’re a manufacturer, food producer, or tech company in Pierce County looking to export, the pathway exists — and it’s been built over decades, not months.
