2. The granting of asylum to refugees is a peaceful and humanitarian act and shall not be regarded as an unfriendly act by any Member State. 3. No person shall be subjected by a Member State to measures such as rejection at the frontier, return or expulsion, which would compel him to return to or remain in a territory where his life, physical integrity or liberty would be threatened for the reasons set out in Article I, paragraphs 1 and 2. 4. Where a Member State finds difficulty in continuing to grant asylum to refugees, such Member State may appeal directly to other Member States and through the OAU, and such other Member States shall in the spirit of African solidarity and international co-operation take appropriate measures to lighten the burden of the Member State granting asylum. 5. Where a refugee has not received the right to reside in any country of asylum, he may be granted temporary residence in any country of asylum in which he first presented himself as a refugee pending arrangement for his re-settlement in accordance with the preceding paragraph. 6. For reasons of security, countries of asylum shall, as far as possible, settle refugees at a reasonable distance from the frontier of their country of origin. ARTICLE III PROHIBITION OF SUBVERSIVE ACTIVITIES 1. Every refugee has duties to the country in which he finds himself, which require in particular that he conforms with its laws and regulations as well as with measures taken for the maintenance of public order. He shall also abstain from any subversive activities against any Member State of the OAU. 2. Signatory States undertake to prohibit refugees residing in their respective territories from attacking any State Member of the OAU, by any activity likely to cause tension between Member States, and in particular by use of arms, through the press, or by radio. ARTICLE IV NON-DISCRIMINATION Member States undertake to apply the provisions of this Convention to all refugees without discrimination as to race, religion, nationality, membership of a particular social group or political opinions. ARTICLE V VOLUNTARY REPATRIATION 1. The essentially voluntary character of repatriation shall be respected in all cases and no refugee shall be repatriated against his will. 2. The country of asylum, in collaboration with the country of origin, shall make adequate arrangements for the safe return of refugees who request repatriation. 3. The country of origin, on receiving back refugees, shall facilitate their re-settlement and grant them the full rights and privileges of nationals of the country, and subject them to the same obligations. 4. Refugees who voluntarily return to their country shall in no way be penalised for having left it for any of the reasons giving rise to refugee situations. Whenever necessary, an appeal shall be made through national information media and through the Administrative Secretary-General of the OAU, inviting refugees to return home and giving assurance that the new circumstances prevailing in their country of origin will enable them to return without risk and to take up a normal and peaceful life without fear of being disturbed or punished, and that the text of such appeal should be given to refugees and clearly explained to them by their country of asylum.
