U.S. President Barack Obama unveiled a new national security strategy blueprint on Friday, reaffirming his commitment to end North Korea's nuclear program and make the world free of nuclear weapons.

   "No threat poses as grave a danger to our security and well-being as the potential use of nuclear weapons and materials by irresponsible states or terrorists. We therefore seek the peace and security of a world without nuclear weapons," Obama said.

   "Our commitment to the denuclearization of the Korean Peninsula is rooted in the profound risks posed by North Korean weapons development and proliferation," he said in the National Security Strategy report sent to Congress.

   The U.S. administration is required to periodically update the report to outline the country's national security concerns, priorities, goals and strategies. Friday's report is the first since the last one published in 2010.

   In the report, Obama also reaffirmed his "pivot to Asia" policy.

   "Over the next 5 years, nearly half of all growth outside the United States is expected to come from Asia. That said, the security dynamics of the region, including contested maritime territorial claims and a provocative North Korea, risk escalation and conflict," Obama said.

   "American leadership will remain essential to shaping the region's long-term trajectory to enhance stability and security, facilitate trade and commerce through an open and transparent system, and ensure respect for universal rights and freedoms," he said.

   In order to realize the vision, Obama said the U.S. is modernizing its alliances with South Korea, Japan, Australia and the Philippines and enhancing the interactions among them to ensure they are fully capable of responding to regional and global challenges.

   Obama also renewed security commitment to South Korea and other Asian allies.

   The U.S. welcomes the rise of a stable, peaceful, and prosperous China, Obama said, adding that he hopes to develop a constructive relationship and work together with China on climate change, public health, economic growth, and the denuclearization of the Korean Peninsula.

   At the same time, Obama said the U.S. will manage competition with China "from a position of strength" while insisting that China uphold international rules and norms on issues ranging from maritime security to trade and human rights.

   "We will closely monitor China's military modernization and expanding presence in Asia," Obama said. "On cyber-security, we will take necessary actions to protect our businesses and defend our networks against cyber-theft of trade secrets for commercial gain whether by private actors or the Chinese government."
