Zimbabwe is telling its police officers to lighten up - with smiles.

The southern African country is launching a training program to get police to "say cheese" more often in hopes of winning over tourists who go to see Victoria Falls and other sights.

Ziyambi Ziyambi, deputy home affairs minister, said Thursday that a smile "can change a lot."

Tourists driving through the country often encounter roadblocks with grave-faced officers. Zimbabwe's economy is struggling, and the government is trying to revive its tourist industry to bring in badly needed revenue.

Some Zimbabweans are skeptical about the smile policy, citing concerns about police corruption. Willard Shupai, a resident of the capital, Harare, says what really makes a police officer smile is money.
