Trump made the phone call to President Xi Jinping of China, appealing for more help to restrain what he called the "growing threat" posed by North Korea, a White House spokesman said. Since then, the White House has become frustrated China was not doing enough to pressure North Korea to abandon its ballistic missile and nuclear programs.
According to a readout of a July 2 call between Trump and Xi released by the Chinese state news agency Xinhua, "bilateral relations have also been affected by some negative factors, the Chinese side has indicated to the USA side".
The two leaders are set to meet on the sidelines of the G20 summit which will be held in the northern German city of Hamburg on Friday and Saturday of this week.
China has repeatedly stated its opposition to the U.S. Terminal High Altitude Area Defense (THAAD) anti-missile system and has called for its deployment to stopped, and the missiles already installed to be removed.
Citing senior administration officials, the New York Times yesterday reported that Trump had warned Xi that the United States was prepared to act on its own if China failed to compel North Korea to submit.
In related news, the American media reported that on July 2 American destroyer USS Stethem sailed within 12 nautical miles of Triton, an island in the Paracel Archipelago (called Xisha by the Chinese) in the South China Sea that is occupied by China.
But on June 21, Trump sent a tweet saying Chinese efforts to restrain North Korea had "not worked out", while adding he greatly appreciated that they had "tried".
China lashed out at the USA on Friday in protest at an apparent sea change in the Trump administration's policy towards Beijing as the White House prepared to slap punitive restrictions on Chinese steel imports, agreed an arms deal with Taiwan, and sanctioned a Chinese bank, the Financial Times reports.
The resumption of Freedom of Navigation operations, like that which so irked China on Sunday, and other recent needles are signs that Trump no longer feels it is worthwhile to give Beijing a free pass for assistance with North Korea.

Japan's Chief Cabinet Secretary Yoshihide Suga told a news conference the two countries and South Korea will have a trilateral summit at the G20 meeting, but he didn't want to speculate on what might be said there.
During the conversation, Xi stressed that important results have been achieved in bilateral relations since his meeting with Trump in Florida in April.
Trump has pressed Xi to use China's diplomatic and economic clout over North Korea to pressure the Stalinist state to abandon its nuclear programme, but the U.S. leader tweeted last month that Beijing's efforts had failed.
The sale came the same day as new sanctions were announced on China's Bank of Dandong, which the U.S. accuses of supporting illegal North Korean financial activity.
North Korea was a prominent topic of discussion when Trump welcomed South Korean President Moon Jae-in at the White House Thursday night, although the Korean leader favors a diplomatic approach rather than military engagement.
The U.S. Department of the Treasury placed sanctions on China's bank of Dandong due to suspicions of illicit transactions with North Korea.
And Washington has taken a series of additional steps recently seen as affronts to Beijing, including accusing the Chinese government of human rights violations and selling $1.4 billion in weapons to Taiwan, which China regards as its territory.
On Sunday, the United States navy conducted its second so-called freedom of navigation operation in less than six weeks to challenge Chinese sovereignty in the South China Sea. The island is administered by China since several decades. The Chinese foreign ministry branded the United States foray "a serious political and military provocation" and reported that Chinese warships and fighter planes were sent to warn off the USA destroyer.
