By the 6th century, Gaya could not risk hostility of either Baekje or Silla. Ara Gaya put a great deal of effort into pursuing a diplomatic solution for maintaining its independence, including hostage of international meetings with Baekje, Silla and Japan.

But Gaya was too weak by that time; Northwestern Gaya states fell to Baekje influence and southeastern Gaya states fell to Silla influence. Ara Gaya sought its independence by allying with Goguryeo and asked Goguryeo to invade Baekje in 548. But this attempt to weaken Baekje influence failed as Goguryeo failed this campaign.
