Malam Garba Shehu, the president’s Senior Special Assistant on Media and Publicity in a statement in Abuja, said the President made the call when he met with Nigerians in South Africa, in Pretoria on Friday.

President Buhari charged them to be diligent, focused and resourceful in all their engagements, especially in improving their net worth through learning new skills, good education and building their networks positively.

He said: “First, you are our Ambassadors and the face of our country to the world wherever you are. The world is therefore, watching you and would make judgments on Nigeria based on your comportment and actions.

“Second, in whatever legitimate engagement you find yourself, you must strive to excel and be the best.

“Third, while you are out in the Diaspora, do not forget home. You represent some of the best human asset that Nigeria has. With your education and exposure to the world, you are at the cutting edge of technology.

“I, therefore , urge you to use your resources, skills and talents to help the development of Nigeria,’’ he said.

President Buhari told the gathering, which included students, traders, medical doctors, clerics and academics, that an agency had been established by the Federal Government, headed by Hon. Abike Dabiri-Erewa, to guide them on how to actualize their contributions to the country.

The President said he was shocked at the outbreak of xenophobic attacks on Nigerians in South Africa.

“The recent acts of xenophobic attacks on our compatriots and other Africans in South Africa are shocking to me, Nigerians and indeed Africa.

“It was an embarrassment to the continent. Let me again use this medium to condole with the families of all those who lost their lives over the years in such tragic incidents. May their souls rest in peace,’’ he added.

President Buhari also commiserated with those who were injured, praying for their quick recovery, and sympathized with those who lost property and other valuables.

“As a government, we are quite disturbed by these very unfortunate events and have taken actions and measures to address this issue and prevent their re-occurrence with the South African government.

“I had earlier directed the evacuation of Nigerians who do not feel safe to remain here. Over five hundred have returned home and are being reintegrated into their communities.

“At this juncture, I wish to express my profound gratitude to Chief Allen Onyeama, the Chairman of Air Peace Airlines, who showed compassion and patriotism by immediately offering to evacuate our Nigerian brothers and sisters who had been affected by these xenophobic attacks,’’ he said.

He assured Nigerians that the South African authorities had expressed their apologies over the incidents and resolved to take necessary steps to end the ugly trend.

“We have just inaugurated the Nigeria/South Africa Bi-National  Commission at the level of Heads of State with a firm determination to further bring our two countries together in a mutually beneficial partnership.

“Let us therefore give peace a chance and pray we have seen the last of this ugly violence,’’ the President said.

President Buhari also called on all Nigerians to be law abiding and respect constituted authorities of other countries.

He urged “the  few that sometimes gives us a bad name, to desist from such misdemeanours and be our good ambassadors’’.

In his remark, the Minister of Foreign Affairs, Geoffrey Onyeama, commended the President for the maturity and diplomatic tact he used in resolving the challenge with the South African government.

He said the government had put in place a mechanism to ensure that the unfortunate incidents were never repeated again.

Members of the Nigerian community thanked the President for the visit, assuring him that they would be more careful in their dealings within the country, and work towards harmony at all times.

The leaders of various communities in South Africa, led by Ben Okoli, commended Chief Onyeama, for his quick intervention, and the historic roles the Nigerian High Commissioner, Amb. Kabir Bala and Consul General, Mr Godwin Adama, played in protecting and providing for citizens
