Chinese Foreign Minister Wu Xueqian says the United States shouldn't have suspended efforts to relax the ban on high-technology exports to his country.

Naturally, we hope the situation will change as soon as possible, said Mr Wu, in Washington today for a scheduled meeting with President Reagan.U.S. restrictions on high-technology exports are a sore point among American businessmen in China and the Chinese government. Reports that China was selling missiles and other war materiel to Iran prompted the United States late last year to suspend plans to further relax its ban on high-technology exports to China.

Mr. Wu said in New Orleans last week that the question of high-technology exports would be touched upon during his visit to Washington.

In his remarks during a World Trade Center dinner honoring the eight- member Chinese delegation, Mr. Wu said the U.S. and Chinese economies easily could complement each other.

China is the largest developing country in the world. It has rich human and material resources and a large market, he said. But it lacks managerial expertise and technology.

He said the United States is the largest developed nation, with massive

financial strength, well-developed technology and management expertise.

But it is in need of a market and less-expensive labor, Mr. Wu said through an interpreter, arguing that Sino-American trade relations have not taken advantage of the situation.

The two sides need to work together to overcome difficulties and obstacles, the minister said.

The United States is China's third-largest trading partner after Hong Kong and Japan. China is the United States' 16th largest trading partner.

Mr. Wu said two-way trade with the United States exceeded $8 billion - a figure that does not include goods sent via Hong Kong for reshipment to the United States. The U.S. Commerce Department says the United States imported $6.9 billion worth of Chinese goods last year and exported $3.5 billion.
