By Alexandra Alper and David Alire Garcia MEXICO CITY (Reuters) - Mexican Senate committees on Sunday debated an energy bill that would open up the world's 10th-biggest oil producer to private investment by allowing new types of contracts, marking the industry's most dramatic overhaul in 75 years. The bill, announced by centrist ruling party and opposition conservative lawmakers on Saturday, would let private firms partner with ailing state oil firm Pemex via profit-sharing, risk-sharing and service contracts as well as licenses in a bid to boost sagging production. The reform, which would keep ownership of crude in state hands, is at the center of an economic reform drive that President Enrique Pena Nieto hopes will boost lagging growth in Latin America's No. 2 economy. It is much bolder than a draft proposed by Pena Nieto's Institutional Revolutionary Party (PRI) in August, which would have offered profit-sharing contracts and was considered too tame for attracting private firms.
NATO shipments from Afghanistan via Pakistan are due to resume after the end of anti-drone protests, officials said, as US Defense Secretary Chuck Hagel headed to Islamabad for talks on Monday. Hagel, who has been in Afghanistan since Saturday, will meet with Prime Minister Nawaz Sharif in the first visit by a Pentagon chief to Pakistan for nearly four years. Ties between Washington and Islamabad have been deeply troubled over US drone strikes targeting suspected militants in Pakistan's tribal belt, while American officials have long accused Islamabad of allowing Afghan Taliban sanctuaries inside its borders.
