李淵
Diplomatic relations with China continued throughout the Sui Dynasty and the following Tang Dynasty. Gifts were sent with emissaries to Tang in 621 and the Emperor Gaozu sent silks, folding screens of art with an official statement in return. These diplomatic relations continued in the following years and Silla used this relation for asking for Tang's assistance against Goguryeo. Emperor Gaozu of Tang sent governors to both Silla and Goguryeo in 626 to bring about a truce between the two countries, albeit briefly.
