Robert Mugabe is in Singapore for medical treatment.
This is his third visit this year alone.
The 93 year old, was last in Singapore in May for what his spokesman George Charamba said was treatment for eye problems.
The Standard said he had left again for Singapore on Friday for more medical treatment. Information and Broadcasting Services Minister Chris Mushohwe told the newspaper that the President was in Singapore but declined to confirm the reason for the visit.
The ruling ZANU-PF party said on Saturday it had canceled a youth rally scheduled for July 14 due to be attended by the president because he would be out of the country.
Despite growing concerns about his health, Mugabe has taken more than ten trips abroad this year and wants to seek another five-year term in office in 2018.
The government has denied his falling asleep in meetings, saying he is only resting his eyes.
The Zimbabwean president, has according to government data spent $53 million on foreign trips last year, more than double the initial budget of $23 million.
He has ruled the southern African nation since independence from Britain in 1980.
