FACTBOX-Key aims of the WTO ministerial talks

(Reuters) - Ministers from around 30 countries are meeting in Geneva to seek a breakthrough in negotiations on new global free trade treaty, known as the Doha round.

The World Trade Organisation (WTO) talks were launched in the Qatari capital 2001 with the aim of bolstering the global economy by boosting trade and helping poor nations export more.

The ministers meeting this week are not seeking to clinch a final Doha round agreement, but are striving for the outlines of a deal that trade diplomats would then flesh out.

But basic accord on some of the talks' most sensitive issues would be a decisive step forward for the WTO free trade push.

Here are the main results to watch out for:

1 - FORMULAS FOR TARIFF AND SUBSIDY CUTS

Ministers are seeking "modalities" -- or the parameters of an agreement -- in talks over reducing barriers to trade in agricultural and industrial goods.

This would include the formulas for cutting tariffs and subsidies on goods like cotton, rice, shoes, and cars, and designations of what products can be shielded from cuts. Those exceptions are especially important for developing countries.

Diplomats have agreed on the shape or "architecture" of the formulas. Ministers are discussing the numbers to go into them.
