NEW YORK (Reuters) -Oil prices eased about 1% to a one-week low on Tuesday on demand worries following the release of negative economic news from Germany and China, while investors remained cautious ahead of a U.S. Federal Reserve decision on interest rates. Brent futures fell 72 cents, or 1.0%, to settle at $73.19 a barrel, while U.S. West Texas Intermediate crude slipped 63 cents, or 0.9%, to settle at $70.08. In China, the world's second-biggest economy, industrial output growth quickened slightly in November, while retail sales disappointed, keeping alive calls for Beijing to ramp up consumer-focused stimulus as policymakers brace for more U.S. trade tariffs once President-elect Donald Trump takes office for a second time.
