Japan’s Prime Minister Shigeru Ishiba on Saturday renewed a pledge to build up his country’s military and deepen its alliance with the United States under President-elect Donald Trump.

According to Ishiba, breaches of Japanese airspace by Chinese and Russian warplanes earlier this year, not only violated Japanese sovereignty, but also threatened the safety of Japan and are absolutely unacceptable. He said Japan faces growing threats from China’s accelerating military activity around Japanese coasts and from North Korea’s repeated missile firings.
