BEIJING, May 26 (Xinhua) -- Experts from the Chinese mainland and Taiwan are busy preparing for their third meeting on the economic pact designed to boost cross-Strait business, a mainland official said here Wednesday.

The two sides will work hard to achieve the Economic Cooperation Framework Agreement (ECFA) at the next round of talks between the mainland-based Association for Relations Across the Taiwan Straits (ARATS) and the Taiwan-based Straits Exchange Foundation (SEF), said Yang Yi, spokesman with the State Council Taiwan Affairs Office.

Yang said the third meeting will happen this month. It is expected to be held before the ARATS-SEF talks in June.

"At the previous two meetings, the two sides made good progress and reached common understanding on most topics," Yang said.

The early harvest program under the ECFA which lists the first products and services to enjoy duty reduction and market opening is just the first step, Yang noted.

"It will not solve all problems and concerns," he said.
