ROUGH CUT - NO REPORTER NARRATION<br/> <br />STORY: A warm welcome in Tanzania for U.S. President Barack Obama at the end of a tour of Africa where Washington faces competition from China.<br/> <br />Obama's trip to Dar es Salaam occurs three months after a visit by Chinese President Xi Jinping, who came shortly after taking office. Many Africans see the U.S. leader's three-nation tour of Africa as an attempt to play catch-up.<br/> <br />The U.S. president, whose arrival was marked by a 21-gun salute, meets his predecessor, George W. Bush, who is also visiting. They will join a ceremony on Tuesday to lay a wreath to those killed in the 1998 U.S. embassy bombing in Tanzania.<br/> <br />Obama said in South Africa, the second stop of a tour that began in Senegal, that his country was not threatened by China's role but told Africans to make sure any investors were giving back to Africa as well as consuming its raw materials.
