evidence: While Egypt and Sudan generally agreed on the Nile water question, they had failed to resolve a longstanding dispute over the location of their border near the Red Sea, an area called the Hala'ib Triangle.[14] Egypt occupied the disputed territory, but the matter remained ripe for future conflict.[14][32] Al-Bashir revived the controversy as recently as 2010 when he stated that Hala’ib was Sudanese and would stay Sudanese.[14] [...] Sudan has particularly appreciated Egyptian verbal and moral support for its policy in Darfur.[14] Egypt also sent troops to the United Nations–African Union Mission in Darfur.[14] Egyptian investments in Sudan reached US$2.5 billion by 2008 while Sudanese investments in Egypt totaled almost US$200 million.[14] By 2010 Egyptian–Sudanese relations were better than they had been in many years, although several long-term contentious issues, such as the future status of South Sudan, ownership of the Hala’ib Triangle, and use of Nile water, remained unresolved.[14]
