How Trump's stance on China has changed amid North Korea threat The president has been pressuring China for action.

 -- Since Donald Trump took office, his relationship with Chinese President Xi Jinping has changed dramatically as the U.S. attempts to deal with the threat posed by the North Korean regime.

Although Trump was critical of China during the presidential campaign, Xi was one of the first world leaders to visit Trump after the inauguration, and the two even spent time together at Trump's Mar-a-Lago estate in Florida.

Their burgeoning relationship has not stopped Trump, however, from speaking out against China and Xi. Trump has expressed frustration with China over its reluctance, in his view, to stop military advances by North Korean leader Kim Jong Un.

The Chinese government has suggested its relationship with the Trump administration is starting take a more negative turn. 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 U.S. side."

Here is a review of the various public statements and tweets released by Trump and the White House on China and North Korea.
