Portugal's President Marcelo Rebelo de Sousa on Tuesday acknowledged his country's not always positive colonial past, during a visit to the former colony of Guinea-Bissau. Making the first visit to the country by a Portuguese head of state for 31 years, Rebelo de Sousa said Portugal "fully acknowledges" its colonial past "including those aspects which were not positive". The West African nation of Guinea-Bissau fought a war of independence and became a sovereign state in 1974. Portugal is a bridge between cultures and "it has been throughout its history, not always well, often badly," said the Portuguese leader, who arrived in Bissau Monday for a 24-hour visit after a stay in Cape Verde. Rebelo de Sousa held talks with his Guinean counterpart Umaro Sissoco Embalo. He visited a cemetery where hundreds of Portuguese soldiers who died during the independence war are buried. Rebelo de Sousa also laid a wreath at the tomb of Amilcal Cabral, the Guinea-Bissau independence leader killed in Conakry in 1973. aye/pvh/jj
