The World Trade Organization delivered a long-awaited ruling Friday on government subsidies provided to Airbus that could affect efforts to challenge the company's near-duopoly with Boeing Co. (BA) in the large aircraft market.

The WTO was expected to rule that launch aid provided to Airbus for new aircraft development was illegal, though the European company said Friday that a final decision could take up to five years.

Airbus is a unit of European Aeronautic Defence & Space Co. (EADSY).

However, the confidential findings will be closely tracked amid efforts in China, Russia and Japan to launch new commercial aircraft with government assistance.

Boeing had alleged that subsidies to Airbus were illegal, triggering the complaint from the U.S. government to the WTO. A parallel complaint against alleged illegal subsidies provided to Boeing is also before the Geneva-based organization.

Airbus and Boeing dominate the market for aircraft with more than 100 seats, where financing plays a key role alongside operating performance in the fierce sales battles between the two rivals. Cutting the development cost with low-price loans would reduce the final sale price.

Both companies also tap extensive government sales-financing support from export-credit agencies, which has also been the subject of long-running trade disputes.

The same trade friction has been seen in the regional jet market, which is dominated by Canada's Bombardier Inc. (BDRBF) and Empresa Brasileira de Aeronautica SA (ERJ), also known as Embraer, of Brazil.

Bombardier will secure around one-third of the development cost of its new C-Series aircraft from Canada, the U.K. and the Quebec government. Embraer said it isn't receiving any government development aid.

The Chinese government is backing the new ARJ21 regional jet with partners including General Electric Co. (GE), while Russia's Sukhoi Design Bureau Co. plans to enter the market with its Superjet 100.

In Japan, Mitsubishi Heavy Industries Ltd. last year launched the MRJ regional jet program, and expects to secure one-third of the development cost from the country's economy ministry.

The WTO confirmed that it issued its first ruling in the U.S. complaint against Airbus.

"It's been given to the parties," WTO spokesman Keith Rockwell told Dow Jones Newswires. The content of the ruling is confidential, and won't be publicly released for "quite some time," he said.

The European Commission earlier Friday said it received the long-awaited ruling. The commission, the E.U.'s executive arm, is studying the report and declined to comment further.

Airbus said at a media briefing before the release that a final decision - which could leave the U.S. open to impose sanctions against the European Union - may take another three to five years.

Another WTO panel is expected to issue a preliminary report on the E.U.'s complaint against Boeing in about six months.

Airbus spokesman Rainer Ohler urged an end to the dispute, saying the only solution would come from the negotiating table.

He said that the company's A350 long-range aircraft, which it is developing to compete with the Boeing 787 Dreamliner, isn't part of the dispute.
