premise: During a whirlwind visit on Friday morning to China's first national corporation on international engineering projects, Guinea-Bissau President Joao Bernardo Vieira rapped the gavel on two proposed projects: electric power development and water reservoir construction.
  "Please draft out the cooperation plans immediately. What Guinea-Bissau needs most is development, especially better infrastructure facilities," said the 67-year-old at the China Machinery and Equipment Import and Export General Corporation ( CMEC)
  "My biggest wish is to make power supply accessible across the whole country," said Vieira who was here to attend the Beijing Summit of Forum on China-Africa Cooperation slated for Nov. 4-5.
  His visit to CMEC, which established its name in Africa after winning a contract to construct four units of 30 MW hydro-power stations there in 1990s, came two days after an economic and technical cooperation agreement was signed in the presence of Chinese President Hu Jintao. Both sides have yet to disclose the details of the agreement.
