Indonesias history has proven that unity could help face various challenges.
He called on every Indonesian to develop unity and togetherness. "Let us build a synergy although we have different backgrounds," he said.
Indonesia is currently facing various challenges such as a global economic competition, poverty, backwardness, and a social gap, according to the Vice President.
Every citizen must have access to education, health services, and energy, and no region should be isolated any longer, he added.
