Esper Calls Out China's 'Rule-Breaking,' Vows to Protect Pacific Norms Carla Babb WASHINGTON - U.S. Secretary of Defense Mark Esper has warned the world's "free and open" system forged in the wake of World War II is under attack by what he calls China's "rule-breaking behavior" in the Indo-Pacific region. Esper spoke in Hawaii, home to the U.S. Indo-Pacific Command, ahead of travel to Guam and Palau to take part in ceremonies marking the 75th anniversary of the end of World War II. Esper called the Indo-Pacific region the "epicenter" of great power competition, vowing not to "cede an inch" to countries that threaten international freedoms, in an apparent dig at China. "The People's Liberation Army continues to pursue an aggressive modernization plan to achieve a world-class military by the middle of the century," Esper said. "This will undoubtedly embolden the PLA's provocative behavior in the South and East China Seas and anywhere else the Chinese government has deemed critical to its interests." Chinese Defense Ministry spokesman Wu Qian told news media Thursday that the U.S. has "continued to provoke tensions and undermine China's sovereignty and security." He added that current diplomatic relations between the two countries have been "severely damaged." China has made expansive claims over the South China Sea, basing military weapons and aircraft on artificial islands built atop reefs to bolster its territorial claims, which overlap with the territorial claims of other nations. .
