GENEVA, April 7 (Reuters) - Ecuador's measures to restrict imports to defend its balance of payments would affect $4.3 billion of its 2008 imports, or 23 percent of the total, according to a World Trade Organisation report.

Importing shoes to Ecuador will cost an extra $10 a pair

The report, dated April 6 and published on the WTO website, was drawn up in preparation for a meeting on April 22 of the WTO's Committee on Balance of Payments Restrictions, where Ecuador will seek a temporary waiver from WTO rules.

Ecuador, whose trade balance has been battered by the global recession, imposed the restrictions in January on imports from Colombian bubblegum to Chinese shoes.

The move has strained relations with its Latin American trading partners, and Quito threatened last month to withdraw the world's largest banana exporter from the four-nation Andean trade bloc CAN if they reject its move.

CAN also includes Colombia, Peru and Bolivia.

The restrictions cover 8.7 of products imported into Ecuador, with some goods attracting an additional tariff of 30 or 35 percent of value.

Textiles and clothing will pay an extra duty of $12 a kilo, while shoes will pay an extra $10 a pair.

For other products Ecuador has imposed import quotas of 65 or 70 percent of the 2008 value.

The WTO report lays out the impact on exports of Ecuador's major trading partners, and on products.
