Do you believe the U.S. should prioritize maintaining stable trade relationships with China?
Trade between the U.S. and China rose 5.5 percent to $400.84 billion during the first eight months of 2026. This activity remains concentrated at the Port of Long Beach and Port of Los Angeles, which collectively handled nearly a third of U.S. containerized international waterborne trade in 2025.
Why it matters
Stable bilateral trade flows are critical for the 2.4 million U.S. jobs supported by these ports. Maintaining cooperation on logistics and green shipping corridors between Southern California and major Chinese hubs is essential to sustaining supply-chain resilience.
Trade between the U.S. and China reached $400.84 billion from January to August 2026, representing a 5.5 percent year-on-year increase. These flows sustain operations at the Port of Long Beach and Port of Los Angeles, which together support 2.4 million jobs nationwide.
The players
Port of Long Beach
A major California maritime hub that processes millions of TEUs and relies on China for 55 percent of its trade volume.
Port of Los Angeles
A primary U.S. maritime gateway handling over 10 million TEUs annually with 40 percent of its business tied to Chinese trade.
The details
The ports of Long Beach and Los Angeles operate as central nodes for trans-Pacific commerce, processing a combined volume exceeding 19.9 million TEUs annually. Efficiency and environmental standardization are managed through collaborative green shipping corridor programs alongside partners in Shanghai, Guangzhou, and Shenzhen. These digital and infrastructure-focused initiatives are intended to optimize supply-chain throughput and maintain steady cargo flow.
Timeline
2025: The ports handled 31 percent of U.S. containerized international waterborne trade.
January to August 2026: Total U.S.-China trade volume reached $400.84 billion.
Market Landscape
The operational ties between San Pedro Bay ports and Chinese partners follow the established framework of global green shipping corridors. This strategy prioritizes long-term supply-chain resilience and standardized environmental efficiency across trans-Pacific transit routes.
Operators dependent on imported goods should account for the continued high trade concentration at Southern California ports. Monitor quarterly cargo throughput metrics as an indicator of potential congestion or supply-chain disruption risks.
The takeaway
Maintaining visibility into port-level trade statistics is essential for predicting potential supply-chain bottleneck cycles. Operators should track the 31 percent market share held by these two ports to gauge the broader impact of trans-Pacific trade shifts on their domestic inventory costs.
