SAN SALVADOR (Reuters) - Mexican President Felipe Calderon on Tuesday added his voice to regional condemnation of Colombia's military strike on rebels inside Ecuador, and called on the two countries to resolve the problem peacefully.

"We coincide in the rejection of any action that constitutes a violation of territorial sovereignty," Calderon said after a meeting with Salvadoran President Tony Saca in which the two leaders discussed the crisis.

Colombia bombed neighboring Ecuador's territory on Saturday to kill a senior leftist FARC guerrilla, leading Ecuador's ally Venezuela to warn that war could break out in the region. Both Ecuador and Venezuela have mobilized troops.

Mexico's criticism of Colombia came after Brazil condemned the bomb attack on Monday and called on Bogota to offer an explicit apology.

Nicaragua has also condemned Colombia's killing of the rebel commander, and former Cuban President Fidel Castro called the incident a "monstrous crime."

Calderon said Mexico would try to help Colombia and Ecuador resolve the crisis.

"We will spare no effort so that the Colombian and Ecuadorean governments normalize relations as soon as possible through dialogue and diplomatic channels," Calderon said.

Calderon may meet with Colombian President Alvaro Uribe at a regional summit being held in the Dominican Republic on Thursday and Friday, Mexican state news agency Notimex reported.

Dominican government sources have said both Venezuelan President Hugo Chavez and Ecuadorean President Rafael Correa might attend the summit.

The United States accused Canada of misinterpreting the agreement to give its exporters an unfair advantage.

The ruling marked a victory for the Western Canadian provinces of British Columbia and Alberta when the panel found against the U.S. claim that the provinces owed millions of dollars in export taxes aimed at limiting export surges.

Under the deal, Canadian lumber exporters can either pay export charges of up to 15 percent based on their selling price to the United States, or cap the charge at 5 percent along with an export quota that restrains volume.

British Columbia has traditionally produced about half of all the softwood that Canada exports to the United States.

However, the court found that Quebec and Ontario in Canada's east, which are also big producers and use the quota option to limit their exports, had sent too much lumber south.

"Under the panel decision, producers in the east of Canada will be penalized for over-shipping their allowable quota," said Zoltan van Heyningen, executive director of the Coalition for Fair Lumber Imports, the U.S. industry group that has been driving the complaints.

Canada claimed at least partial victory and said the ruling was a healthy step for the bilateral 2006 agreement, which was designed to avert more years of long, expensive lumber lawsuits.

"While Canada believes that it has fully complied with the agreement, we respect the tribunal's ruling ... Today's decision provides clarity with respect to the implementation of the SLA (Softwood Lumber Agreement) in the future," said Canadian Trade Minister David Emerson.

The United States had argued that the starting point for calculating export charges and volumes should be the first quarter of 2007, while Canada argued it should be July 2007. The court sided with the United States on that issue.

The two countries have one month to propose possible remedies for the overshipping issue, which might entail docking future exports, Van Heyningen said.

The U.S. coalition said it disagreed with the findings on the western provinces, which it said "let Canada off the hook regarding past collections of 'surge mechanism' export taxes," which they estimated at up to about $85 million.

The Bush administration has filed a separate complaint at the court, alleging that certain Canadian provinces were improperly propping up their lumber industries.

The fertilized eggs were implanted three days after she was dismissed from her job at a bakery in March 2005.

In its ruling Tuesday, the EU court said that under such an argument, women could delay having fertilized eggs implanted for years and claim unfair dismissal by saying they are pregnant.

Rather, the EU high court ruled that the Austrian court need only assess whether in vitro fertilization was considered by her employers as grounds for dismissal. European law bans gender discrimination.
