During Seong's reign, Baekje had led an alliance with the neighboring Silla and the Gaya confederacy to attack the powerful northern kingdom of Goguryeo.
Baekje under Wideok was inimical with both Silla and Goguryeo, launching various battles and border incursions against the rival kingdoms.
To avoid isolation, and to strengthen the royal position against the power of the aristocracy, he maintained friendly relations with the Chinese dynasties of Chen, Northern Qi and Sui.
In the same year, a Sui warship happened to run aground on Jeju Island, which was ruled by the Baekje dependency of Tamna.
In 1995, a stone relic box was found in a Baekje-era Buddhist temple in Buyeo County, South Chungcheong Province.
