Bras, flax yarn and T-shirts became on Monday the latest Chinese textile imports into the European Union to hit their annual quota ceilings agreed between Brussels and Beijing, an EU official said Monday.

"The quotas for bras, flax yarn and T-shirts were filled this morning," the official said, speaking on condition of anonymity.

That means that six out of 10 textile categories covered by EU import quotas have now been met.

The quotas for blouses, men's trousers and pullovers were also already reached earlier this month, leaving millions of garments stranded at EU customs and throughout supply chains.

That has stoked the ire of some big EU retailers awaiting deliveries ahead of the key back-to-school period.

But the official stressed that it was normal that the 2005 quotas were already filling up because importers have to make orders month ahead of delivery time.

The EU and China agreed to a broad textile trade agreement in June setting annual restrictions on 10 categories of Chinese imports, which had been surging since the beginning of the year following the end of an international quota system.

A delegation of EU officials are to head to China on Wednesday to hold talks on the quotas.

Facing growing pressure from retailers, Brussels has said that it is willing to be flexible about quotas.

The June deal, which averted a trade war with the growing Asian economic giant, was struck after the EU textile industry lobbied the European Commission to take action to hold back the wave of cheap Chinese imports flooding into the 25-nation block.

But European retailers and a growing number of EU member states -- mostly with small textile industries -- are now pressuring the commission to review the quotas it negotiated only two months ago, in what was hailed at the time as an important diplomatic success for the EU.
