(Reuters) -Investors are hopeful that U.S.-China trade talks this weekend will cool a trade war between the world's two largest economies and dispel some of the uncertainty clouding financial markets, though few expect a major breakthrough just yet.

The U.S. and China are set to begin trade talks in Geneva, Switzerland. Both sides will first want to make sure the other is serious about negotiating a future deal. Possible topics for discussion include lowering the current tariff rates of more than 100% and a litany of non-tariff trade barriers.

China and the United States start their first major Trade War Two meeting on Saturday to pull back from what analysts describe as a lose-lose situation for their economies, without much clarity on what a win would look like for either side.
