Chinese President Hu Jintao is opposing US demands to significantly revalue China's currency as a way of reducing his country's vast trade surplus with the United States.
Speaking at a Boeing facility north of Seattle on the eve of a White House summit with President Bush, Mr Hu said he wanted to make foreign-exchange markets more efficient. But he said China was not ready for a drastic change in the value of renminbi currency, also known as the yuan.
"Our goal is to keep the renminbi exchange rate basically stable at adaptive and equilibrium levels," Mr Hu said.
"China will continue to firmly promote financial reforms, improve the renminbi exchange rate-setting mechanism, develop the foreign exchange market, and increase the flexibility of the renminbi exchange rate," he said.
Revaluing the yuan is a key US demand which officials say is vital to make US exports more competitive, erase an advantage Chinese manufacturers currently enjoy and reduce China's bilateral trade surplus, which last year reached $202 billion.
A top US official said this week China's progress on the currency issue had been "agonisingly slow" and that Mr Bush was certain to raise it when the two leaders met at the White House today.
US experts said they did not expect a breakthrough on the exchange rate. Rather, they were hoping for slow, steady progress in the months ahead.
Mr Hu said China did not seek a large surplus. "China takes the trade imbalance between our two countries seriously and works hard to address this issue," he said.
On the other hand, the fault did not all lie on China's side, he said. The United States also needed to act to ease export controls and reduce protectionist measures.
