"Negative factors" loom large before Trump meets Chinese leader

U.S. & S. Korea differ on N. Korea

BEIJING -- Chinese President Xi Jinping warned President Donald Trump on Monday that "some negative factors" are hurting U.S.-China relations, as tensions flare anew over a slew of long-standing sore points.

Xi's comments in a phone call with Mr. Trump follow Beijing's displeasure over U.S. arms sales to rival Taiwan, U.S. sanctions against a Chinese bank over its dealings with North Korea and, most recently, the sailing of a U.S. destroyer within the territorial seas limit of a Chinese-claimed island in the South China Sea.

China's foreign ministry accused the U.S. of violating Chinese sovereignty and disrupting "peace, security and order of the relevant waters" after the U.S. Navy destroyer USS Stethem sailed Sunday within 12 nautical miles of tiny Triton island, which is claimed by China, Taiwan and Vietnam.

China's defense ministry issued a similar statement Monday, saying it would beef up patrols and take precautions commensurate with the threat level to safeguard "national sovereignty and security."

Beijing was also miffed after the State Department gave Beijing a dismal grade last week in a new human trafficking report.

According to state media, Xi told Trump in their call that Beijing expects Washington to continue managing relations on the basis of the "one China" principle that rules out formal contacts with Taiwan, which China claims as its own territory.

Trump's China comments prompt tension over Taiwan

"Xi Jinping emphasized that, since my meeting with the president at Mar-a-Lago, China-U.S. relations have achieved important outcomes," state broadcaster China Central Television reported, referring to Xi's meeting with Trump in Florida in April. "At the same time, bilateral relations have been affected by some negative factors. China has expressed its position to the U.S."

Seeking to lighten the message slightly, Xi also said that China-U.S. relations had achieved "important outcomes" since the Florida meeting.

It's unclear whether any of those issues will come up in discussions at the G-20 summit in Germany this week, at which Mr. Trump and Xi are expected to hold a bilateral meeting.

But it now appears that China is pushing back against the U.S. pressure, setting the stage for a potential confrontation.

Trump says patience with North Korea is over

Mr. Trump and his top aides have done little to hide their irritation over what they see as the reluctance by China, North Korea's main economic partner, to tighten the screws on Pyongyang over its nuclear and missile programs.

Until recently, American officials had been describing China as a partner in their strategy to prevent North Korea from developing the ability to strike the U.S. mainland with nuclear weapons. While China has agreed to sanctions, it is wary of measures that could cause the regime's collapse, leaving a united, U.S.-backed Korea on its border.

However, Mr. Trump hinted last month at his loss of patience, tweeting that his bid to secure a tougher Chinese approach "has not worked out."

Asked about the state of ties, Chinese foreign ministry spokesman Geng Shuang said Monday that it was normal to encounter "some issues in the process of developing the bilateral relationship."

"We believe that the significance of our bilateral relationship has already exceeded the bilateral scope and is exerting important influence on the development of the whole world," Geng told reporters at a regularly scheduled press briefing.

"On our part, we are willing to develop the bilateral relationship based on non-confrontation, mutual benefit and mutual trust, expand cooperation and properly manage differences between the two countries so as to further advance the bilateral relationship."
