War fears complicate sanctions moves on Iran

By Sophie Walker - Analysis

LONDON (Reuters) - A U.S.-led drive for tougher sanctions on Iran over its nuclear program is being hampered by differences among world powers and suspicions that Washington could use the failure of sanctions to justify military strikes.

The five permanent members of the United Nations Security Council, plus Germany, have agreed to draft a new resolution on imposing wider financial, trade and visa curbs to increase pressure on Tehran to stop enriching uranium.

But Russia and China have long taken a less hawkish approach than that adopted by the United States and largely backed by Britain and France. Differences have also emerged between Germany, France and Britain over how fast to proceed.

The United States has said military action should not be excluded if Iran does not halt enrichment, a process the West fears will yield atom bombs. Iran, a major oil exporter, says its work is intended only to produce electricity.

Russia and China's concerns have been partly driven by commercial ties. Now debate over a separate round of European Union trade sanctions has exposed schisms among major EU countries, political analysts say.

"We're in a bit of a mess. The Americans have shifted the debate away from nuclear proliferation and the Europeans don't know how to deal with that," said Ali Ansari, director of the Institute of Iranian Studies at the University of St Andrews in Scotland.

Washington now lists Iran's nuclear activity as just one of many grievances, alongside accusations that Tehran is funding Shia militant groups in Iraq.

Some political analysts suggest Washington could seek to use any failure to impose harsher sanctions, which would expand on two batches of limited measures adopted within the past year, to strengthen its case for military strikes against Iran.
