North Korea's Supreme Leader Kim Jong Un has announced via North Korean state media that he received a personal letter from President Donald Trump.

Although no official details of the content of the letter have been released, Kim praised Trump's "extraordinary courage." Kim also he said he would "seriously contemplate it."

Press Secretary Sarah Sanders said that the correspondence between the two leaders is still ongoing. The letter comes after Kim recently met with Chinese President Xi Jinping.

Earlier this month, Trump said he received a "beautiful" letter from Kim.

Trump and Kim have been in a series of political negotiations. Trump wants Kim to end his nuclear testing program, while Kim wants Trump to reduce U.S. sanctions on the country. In February, the two sides failed to come to a deal on the issue in Hanoi, Vietnam.

Watchdog Human Rights Watch (HRW) has criticized Trump in his negotiations with Kim. HRW believes that Trump should do more to point out human rights abuses in North Korea and not try to appease the North Korean leader.

In May, Trump met Japanese President Shinzo Abe, where he downplayed recent North Korean missile tests. Trump's goal of acting nice with North Korea to get a nuclear deal could be uncomfortable for other countries in the East Asia region, such as Japan.

In September 2018, Trump joked in front of a crowd that "we fell in love" due to the letters being exchanged between himself and Kim.
