(Adds Shell CEO para 4)

VIENNA, March 4 (Reuters) - The first train at Qatar's gas-to-liquids plant will start in 2010, Qatari Oil Minister Abdullah al-Attiyah said on Tuesday.

The Pearl GTL plant to make super-clean fuels is Shell's (RDSa.L) largest foreign investment and will be the world's largest such plant. Spiralling costs have taken the price to $18 billion from an original budget of $5 billion.

Attiyah said he had met with Shell Chief Executive Jeroen van der Veer on Monday.

"We met with van der Veer yesterday, and had a long discussion on the latest at Pearl," he said. "I am satisfied...its on schedule. The first train will start in 2010."
