The militaristic nature of Goguryeo frequently drew them into conflicts with the dynasties of China.{{citation needed|date=August 2017}} In the times when they are not in war with China, Goguryeo occasionally [[Imperial Chinese tributary system|sent tributes]] to some of the Chinese dynasties as a form of trade and nonaggression pact. Like Buyeo before it, Goguryeo alternately offered tribute to and raided China.<ref>{{cite book |last1=Nelson |first1=Sarah Milledge |title=The Archaeology of Korea |date=1993 |publisher=Cambridge University Press |page=170}}</ref> These activities of exchange promoted cultural and religious flow from China into the Korean peninsula. Goguryeo has also received tribute from other Korean kingdoms and neighboring tribal states, and frequently mobilized Malgal people in their military. Baekje and Goguryeo maintained their regional rivalry throughout their history, although they eventually formed an alliance in their wars against Silla and Tang.{{citation needed|date=August 2017}}
