President Joao Lourenco pledged on Monday to kickstart the ailing Angolan economy with a push to attract foreign investment to end its "excessive" dependence on oil revenue and return to growth.Delivering his state of the nation address to parliament, Lourenco also vowed to continue a crackdown on corruption that has contrasted sharply with the approach of his graft-tainted predecessor Jose Eduardo dos Santos."We will support the Attorney General's office and the Criminal Investigation Service responsible for the fight against corruption, and economic and financial crimes," he told lawmakers in the capital Luanda."We will also update anti-corruption legislation to make it more effective."Since coming to power last year, Lourenco quickly asserted his authority and began to dismantle his predecessor's empire including deposing Dos Santos' daughter from the helm of state oil giant Sonangol.Prosecutors last month remanded Dos Santos' son Filomeno in custody in a $1.5 billion graft probe linked to his time at the head of the country's sovereign wealth fund.

Angola's economy sank into recession in 2017, shrinking 2.1 percent according to official statistics.The economy recovered modestly in 2018 but remains weighed down by an 8 percent contraction in the oil industry, Lourenco said."2019 should have more positive growth with a recovery in the oil and non-oil sectors," he said. "Despite only being in my first year, I took office resolving to fix the people's problems and... to diversify the economy."
