North Korea's nuclear and missile programs pose an ongoing threat to the region and the international community, U.S. Secretary of State Antony Blinken said Thursday.

The top U.S. diplomat also highlighted the need to strengthen the U.S.-Japan alliance to meet such threats.

"Meanwhile, the DPRK's unlawful nuclear, missile programs pose an ongoing threat. And we saw that again this week with the most recent launch," Blinken said, referring to North Korea's test launch of a self-claimed hypersonic missile Wednesday (KST).

Blinken made the remarks at the start of annual security consultative talks with his Japanese counterpart, Yoshimasa Hayashi, which also involved U.S. Defense Secretary Lloyd Austin and Japanese Defense Minister Nobuo Kishi. DPRK stands for the Democratic People's Republic of Korea, the North's official name.

Blinken noted that threats facing the allies included what he called China's "provocative actions" in the region and Russia's military buildup along the Ukraine border.

"So, to address these evolving threats, our alliance must not only strengthen the tools we have but also develop new ones," Blinken told the virtual meeting. "And I think that's really the focus of the discussions that are about to happen."

Blinken earlier condemned the North Korean missile test while holding a telephone conversation with his Japanese counterpart.

Austin reiterated challenges posed by North Korea and others in the Indo-Pacific region.

"We're meeting against the backdrop of increased tensions and challenges to the free and stable and secure Indo-Pacific region that we both seek ― challenges posed by North Korea's nuclear ambitions and by the coercive and aggressive behavior of the People's Republic of China," he said at the top of the two-plus-two meeting.

"So together we are taking bold steps to improve our alliances, bolster our readiness and strengthen what I call integrated deterrence," he added.

This week's missile test marked North Korea's first missile launch since October. Pyongyang claimed to have successfully tested its first hypersonic missile in September. (Yonhap)
