The status of U.S. and Chinese military relations appears to be deteriorating less than one week after the Trump administration imposed sanctions on Beijing for its purchase of Russian weapons and equipment.

On Tuesday, the U.S. Navy amphibious assault ship USS Wasp was denied a port call in Hong Kong that was planned for October, Pentagon spokesperson Lt. Col. Dave Eastburn told ABC News. Days earlier, China summoned the U.S. ambassador, recalled its navy chief from a visit to the U.S. and postponed military talks scheduled to take place in Beijing this week.

The souring of relations followed a decision by the Trump administration last Thursday to sanction a Chinese military body and its director for "significant transaction" with Russia's defense and intelligence sectors -- which is prohibited under a new law passed by Congress last August called Countering America's Adversaries Through Sanctions Act, or CAATSA.

Last week's announcement was the first use of the new sanctions authority meant to "impose costs upon Russia," according to a senior administration official.

China was sanctioned for its purchase of Russia's S-400 missile system and Sukhoi Su-35 combat aircraft, perhaps leading nations like India and Turkey to wonder if they could also face sanctions for similar purchases from Moscow.

In the aftermath of the announcement, Beijing called on the U.S. to "immediately correct its mistake" and revoke the sanctions, adding that the Chinese military reserved the right to take further countermeasures, according to the South China Morning Post.

Asked if Beijing's decision to postpone bilateral military talks was a "setback" for U.S. and China relations, Defense Secretary James Mattis said, "It's too early to say."

"We're still sorting this out," Mattis told reporters at the Pentagon on Monday. "We believe that we do have to have a relationship with China, and Secretary Pompeo and I are of one mind on this. And so we're sorting out the way ahead right now."

Tensions continued to rise after an announcement by the U.S. late Monday that the State Department had approved the possible sale to Taiwan of spare parts for F-16 fighter jets and other military aircraft.

"This proposed sale will contribute to the foreign policy and national security of the United States by helping to improve the security and defensive capability of the recipient, which has been and continues to be an important force for political stability, military balance, and economic progress in the region," the State Department said in a release.

In contrast, China's Foreign Ministry spokesman Geng Shuang called the $330 million sale a serious breach of international law and harmful to Chinese sovereignty and security interests, Reuters reported.

The deteriorating military relations come amid open hostility on many fronts.

President Trump used his address to the United Nations General Assembly on Tuesday to bash China for intellectual property theft and tariffs on U.S. goods, saying "China's market distortions and the way they deal cannot be tolerated."

Washington and Beijing have also spared recently on the militarization of the South China Sea and the imposition of sanctions against North Korea.

Speaking at the University of Louisville on Monday morning, CIA Director Gina Haspel accused China of "working to diminish U.S. influence" while expanding its own.
