LONDON, Feb 3 (Reuters) - Brent crude oil dropped to a two-week low on Monday below $106 a barrel as weak factory data from China stoked concerns about demand growth, but fresh violence in Iraq and Syria limited the fall.

China's factory growth eased to a six-month low in January, in line with expectations, hurt by weaker local and foreign demand and by worries of a wide slowdown across emerging markets. That weighed across most markets such as Asian shares and base metals as investors found a new reason to sell high-risk assets.

Brent crude slipped 45 cents to $105.95 a barrel by 1334 GMT. U.S. oil rose 9 cents to $97.58.

Emerging market stocks and currencies have dropped in the past weeks as investors have cut their financial bets in developing nations in anticipation that the United States will continue to move to less easy monetary policy.

"One of the main negatives that has engulfed the oil complex has been signs of the slowing of the Chinese economy...the main oil demand growth engine of the world," said Dominick Chirichella, a senior partner at Energy Management Institute.

"With all of the negativity coming from the global equity markets the short term oil fundamentals are going to have to improve to push the complex considerably higher from current levels."

The slowdown in emerging nations may cap gains in oil demand growth, which has been driven primarily by China over the past decade while consumption slowed in the West, often called the OECD (The Organisation for Economic Cooperation and Development) nations, Barclays said in a note.

While the West is improving, it may not help overshadow the slowdown in emerging nations, Barclays added.

The potential impact of political tensions on oil supplies are meanwhile expected to keep a floor under prices.

In Iraq, the army intensified its shelling of Falluja in preparation for a ground assault to regain control of the city, which has been under the control of militants for a month.

In Syria, military helicopters dropped more improvised "barrel bombs" on the northern city of Aleppo, a monitoring group said, bringing the death toll to at least 83 people.

Syria is not vital in terms of oil shipments, but markets have been worried that the crisis there could spill across the Middle East to engulf major exporters.
