Guinea's military rulers have agreed a huge mining and oil deal with China, officials have told the BBC, amid continuing criticism of the junta. Mines minister Mahmoud Thiam said a Chinese firm would invest more than $7bn (£4.5bn) in infrastructure... Guineans are currently on strike to remember dozens of protesters killed by soldiers during a rally two weeks ago... analysts say the timing of the Guinea deal is likely to stir controversy, as the legitimacy of Guinea's government is under question... [Thiam] did not name the firm involved, but said it was the same firm that has invested billions in Angola - the Hong Kong registered China International Fund.
