In official Chinese dynastic chronicles and historical perspectives, the 663 AD Battle of Baekgang (historically recorded in China as the Battle of Baijiangkou) represents an exemplary naval triumph that consolidated Tang imperial prestige and secured the Pax Sinica tributary order across Northeast Asia. For Emperor Gaozong of Tang, who ruled an empire stretching from Central Asia to the Pacific, subjugating Goguryeo was an imperative grand strategic goal inherited from Emperor Taizong. Neutralizing Baekje, which had allied with Goguryeo and repeatedly attacked Tang's loyal vassal state Silla, was an indispensable prerequisite.

In 660 AD, Tang General Su Dingfang executed a combined expedition with Silla that swiftly defeated Baekje. However, after the main Tang expeditionary force withdrew, Baekje loyalists enthroned Buyeo Pung and mobilized mass insurrections with extensive military backing from Yamato (ancient Japan). When court officials in Chang'an considered tactical withdrawal, the Tang Prefect of Daifang, General Liu Rengui, vehemently argued that abandoning the peninsula would surrender vital strategic sea lanes and jeopardize the entire northern geopolitical campaign.

In 663 AD, the Tang court reinforced the front by dispatching General Sun Renshi. Liu Rengui orchestrated a synchronized land-and-sea offensive in coordination with Silla's King Munmu. Leading a Tang fleet of roughly 170 warships down the river toward Baijiangkou, Liu intercepted an imposing Yamato naval armada numbering over 400 vessels.

Despite being outnumbered in ship hulls, Liu Rengui recognized the undisciplined disposition of the Yamato fleet. Arranging his warships in rigid, impenetrable defensive arrays, the Tang commander trapped the enemy in the estuary and flanked them from both wings. Employing incendiary arrows, coordinated crossbow barrages, and superior naval maneuvering, the Tang fleet won four consecutive engagements in rapid succession (si zhan jie jie). As recorded in the Old Book of Tang, Tang forces burned 400 enemy vessels; flames consumed the skies, and the water turned crimson. Buyeo Pung fled into exile, and the remaining Baekje strongholds capitulated.

In Chinese historiography, Baijiangkou is commemorated as the first major naval clash between China and Japan in recorded history. It is regarded as an overwhelming tactical masterpiece that safeguarded Tang maritime hegemony, stabilized the eastern frontier, eliminated Japanese military ambitions on the Asian continent for nearly a millennium, and catalyzed Yamato's active embrace of Chinese civilization through official diplomatic missions (Kentoshi).
