With his charity foundation under fire, Bill Clinton is headed to Africa to tout his organization’s good works — and conveniently put himself several thousand miles away from those probing his unorthodox financial activities.

Clinton heads to Tanzania on Wednesday and Thursday, where he’ll highlight Clinton Foundation projects that are meant to boost crop yields, dispense vaccines, and otherwise improve quality of life for the country’s poor.

The former president will be accompanied by daughter Chelsea, who defended the foundation last week when asked about its fundraising, which is getting new attention with impending release of a new book by Peter Schweizer, “Clinton Cash.”

The pair will conveniently be out of the country all the way through May 7 promoting projects that “are improving the lives of thousands of people across Africa,” according to the foundation.

As it happens, “Clinton Cash” is set for official release on May 5.

The trip comes just days after Maura Pally, executive director of the foundation, acknowledged, “We made mistakes,” including “mistakenly” combining government grants with other donations. It is refilling several years’ worth of tax forms.

The trip also takes Bill and Chelsea to Kenya, Liberia and Morocco. They’ll meet with Ebola survivors in Liberia, and tour a school that is part of the foundation’s “No Ceilings” initiative. Hillary Clinton is staying home.

The trip concludes with a Clinton Global Initiative meeting in Morocco, where Clinton will get the chance to mingle with some of the wealthy business and political leaders who steered millions toward the foundation.

Clinton’s p.r. tour isn’t likely to stop the flow of stories questioning possible conflicts of interest surrounding the unique arrangements among the foundation, the $105 million Clinton raked in giving speeches, and his wife’s tenure.

As The Post reported Monday, there is renewed focus on a contribution to the foundation made by Indian politician Amar Singh, who donated as much as $5 million, which would have amounted to his entire net worth.

The foundation reported the contribution as between $1 million and $5 million. Singh, in his own financial disclosure, reported his total net worth as approximately $5 million.

“If true, that meant Singh had given between 20 and 100 percent of his entire net worth to the Clinton Foundation!” according to the book.

In yet another revelation, Vox reported Tuesday that 181 foundation donors also lobbied Hillary Clinton’s State Department, citing disclosure documents.

The list of companies includes giants like Goldman Sachs, Dow Chemical, Boeing and Pfizer.
