1. Chinese Very Large Crude Carriers (VLCCs) have resumed transporting Saudi crude, but a Houthi maritime blockade in the Red Sea has forced a costly overhaul of supply routes [para. 1][para. 2]. This shift uses Egypt as a strategic transfer point, with once direct shipments rerouting around Africa instead of passing through the Bab el-Mandeb Strait [para. 1][para. 4]. The detour for fully laden vessels adds nearly 10,000 nautical miles and roughly one month to trips to Asia [para. 5].
2. The logistics chain relies on the SUMED pipeline, moving crude from the Red Sea coast to Egypt's port of Sidi Kerir [para. 14][para. 16]. Under one model, Saudi tankers shuttle crude from Yanbu to Egypt where customer VLCCs load it [para. 17]. Under another, buyer's tankers partially load at Yanbu to transit the Suez Canal, then complete loading at Sidi Kerir [para. 18][para. 19][para. 20]. Tankers Olympic Luck and DHT Gazelle followed the partial-loading model, while the COSCO-operated Yuan Xi Hu arrived empty at Sidi Kerir to load its full cargo [para. 2][para. 19][para. 20][para. 21].
3. The disruption severely impacted traffic and security. Vessel transits through the Bab el-Mandeb Strait fell about 38% compared to the pre-blockade period, reaching the lowest daily volume of 2025 on August 3 [para. 11]. Insurance rates in the Red Sea have nearly doubled as risks spiked, highlighted by the Houthi sinking of an Indian cargo ship [para. 8][para. 10]. The Houthis have not offered exemptions for Chinese vessels at Saudi ports, prompting companies to reduce Red Sea traffic [para. 9].
4. The shift created new logistical bottlenecks. The port of Sidi Kerir reached near-full operating capacity with seven vessels at anchor on August 5, up from a usual range of one or two [para. 22]. To support the shuttle trade, Saudi Arabia has deployed at least four of its own VLCCs and chartered vessels from South Korea's Sinokor Merchant Marine to run between Yanbu and Ain Sukhna [para. 23][para. 24][para. 25].
5. The disruption directly affects Chinese energy security. Commercial crude inventories fell below 25 million metric tons by July 31, from about 30 million at the start of the year [para. 29][para. 30]. The inventory index shows storage tanks were just 51.64% full, compared to 58.1% in March, signaling a pressing need to rebuild reserves [para. 30]. The market is described as "highly anxious," with few effective short-term responses available to secure supply [para. 31].
6. Chinese state-owned shippers, including COSCO and China Merchants Group, had paused loadings from Saudi Arabia after government guidance to avoid risk areas including Yanbu and the Strait of Hormuz [para. 7]. While Chinese refiners are still formally evaluating the two-stage loading model, the deployment of the COSCO-operated Yuan Xi Hu at Sidi Kerir indicates active participation in the new, costly supply chain [para. 2][para. 21][para. 28].
7. The sustainability of this workaround remains highly uncertain [para. 32]. Analysts from Kpler suggest that capacity constraints at the SUMED pipeline and Suez Canal make it very difficult to match Saudi Arabia's previous export volumes, which were 4.9 million barrels per day from Yanbu just before the blockade [para. 23][para. 32]. The new route concentrates shipping in geopolitically exposed waterways, which could limit tanker availability and lead to a prolonged structural decline in Saudi crude exports [para. 33].
8. Beijing has publicly called for dialogue to ease Red Sea tensions and respect regional sovereignty, while the complex and costly logistical response continues to evolve amidst the heightened risks [para. 12].
