Several other former Majapahit vassals and colonies had begun to release themselves from Majapahit domination and suzerainty, but Kertabhumi manages to reverse this trend.

He has allied Majapahit with Muslim merchants, giving them trading rights on the north coast of Java, with Demak as its center; in return he asks for their loyalty to Majapahit.

This policy has boosted the Majapahit treasury and power but has weakened Hindu-Buddhism as its main religion because Islam spreads faster.

Hindu-Buddhist followers' grievances later pave the way for Ranawijaya to defeat Kertabhumi.
