Philippine President Rodrigo Duterte said on Monday he may be too busy to accept US President Donald Trump’s invitation to visit the White House because of other travel commitments.

Axarşaz reports citing to Sputnik news on Saturday, the White House said Trump during a phone conversation invited Duterte to visit Washington.
"I cannot make any definite promise," Duterte said as quoted by The New York Times. "I’m supposed to go to Russia, I’m also supposed to go to Israel."

The Philippine president added he is also expected to attend events in China and Cambodia in the near future.

Trump’s invitation to Duterte was criticized by US human rights activists.
