President Muhammadu Buhari on Thursday in Pretoria, South Africa, called for more tolerance, vigilance and heightened security in countries to ensure safety of citizens, noting that competition heralded by globalization, especially with ease in migration, will only get more intense for businesses.

He was responding to questions during a press conference at the Union Building, alongside his host, President Cyril Ramaphosa.

In a statement by Senior Special Assistant on Media and publicity, Malam Garba Shehu, the President said authorities should be more pro-active in detecting early signals of violence between competitors, while migrants and companies should adhere to the local laws of countries.

“Police must be on alert not to allow violence to escalate,’’ he said.

President Buhari said the business world had turned out more dynamic over the years, with foreigners competing with locals in businesses that were initially considered low.

He said the panacea would only be for security agencies to show more interest in market operations, players and likely areas of tensions.

The President likened the situation of Nigerians in South Africa to Ghana where competition at low levels of the economy breeds intense competition, noting that it will keep growing with population explosion.

He told Nigerians living in various parts of the world, especially in South Africa, to adhere with the laws of the country they reside, and ensure compliance with market laws.

“Like it is said, ‘when you are in Rome behave like the Romans’. Always be law abiding,’’ he said.

Earlier in his remark, the President condemned attacks on Nigerians and the burning of their properties in South Africa, describing it as “unacceptable’’, while assuring the South African government that their citizens and businesses in Nigeria will always be protected from harm. He also condemned the reprisal attacks in Nigeria.
