President Donald Trump sent his thanks to North Korean leader Kim Jong Un on Sunday after the country made changes to its military parade in Pyongyang.

North Korea celebrated its 70-year anniversary on Sunday with a show of its military strength but strayed from the traditional display of the country’s intercontinental missiles. The parade instead featured floats and flowers as Kim chose to focus on building economic power.

Trump, who met with Kim for a denuclearization summit in Singapore in June, tweeted his gratitude to the North Korean dictator on Sunday.

“This is a big and very positive statement from North Korea,” Trump tweeted. “Thank you To Chairman Kim. We will both prove everyone wrong! There is nothing like good dialogue from two people that like each other! Much better than before I took office.”

Kim spent the parade with a special envoy from China and other foreign visitors, Reuters reported. The North Korean leader spoke to Chinese parliament chief Li Zhanshu about building economic growth and said he hopes to learn from China.

The parade came only two weeks after Trump announced that he was canceling Secretary of State Mike Pompeo’s diplomatic trip to North Korea. The president tweeted the news on Aug. 24, explaining, “I feel we are not making sufficient progress with respect to the denuclearization of the Korean Peninsula.”

Kim said at the parade that he has taken steps toward denuclearization and planned to uphold the peace resolution, according to Reuters, which cited a Chinese state television report.
