Mr. Trump thinks that Russian and Chinese leaders are smart people.
Former US President Donald Trump believes that Russian President Vladimir Putin and Chinese President Xi Jinping are smart, patriotic people who want their countries to succeed.
"The leaders of the Russian Federation and China love their countries and they want their countries to be successful. And we have Biden, who, in my opinion, is not capable of doing this," Mr. Trump said in an interview with Fox News.
According to Donald Trump, Russian President Putin and Chinese President Xi Jinping are "very smart and powerful people, whether you like it or not".
When it comes to age, Mr Trump said at a rally of his supporters in New Hampshire: "I'll let you know when my health gets worse. I think I can. I don't mind being 80, but now I'm 77, that's a big difference."
It's not about age, people age differently, Mr. Trump declared.
