How much of Slovenia’s trade passes through the Cape of Good Hope?

Estimated value of its trade with each partner that crosses the chokepoint; the percentage is the share of all its trade through the chokepoint, not of the pair’s trade.

1. Slovenia–China$2.9 billion · 53.9%
2. Slovenia–South Korea$445 million · 8.3%
3. Slovenia–India$367 million · 6.8%
4. Slovenia–Japan$280 million · 5.2%
5. Slovenia–Australia$150 million · 2.8%
6. Slovenia–Vietnam$127 million · 2.4%
7. Slovenia–Indonesia$123 million · 2.3%
8. Slovenia–Kuwait$122 million · 2.3%
9. Slovenia–United Arab Emirates$118 million · 2.2%
10. Slovenia–Bangladesh$115 million · 2.1%

Methodology

We estimate the value crossing each chokepoint from BACI trade that travels by sea according to our mode heuristic, split between each country’s ports by where its GDP is generated and which coast is closest, and routed over our own sea network. It is an estimate, not a count of ships. It covers 99.9% of seaborne trade. The approach follows Verschuur, Lumma and Hall (Nature Communications, 2025). Data up to 2024.
