A survey released Thursday by the U.S.-China Business Council found that only around 20 percent of member companies that were polled would use the agreement's dispute settlement process. The agreement creates a multilevel process in which government officials from either side can try to resolve complaints. U.S. companies can raise issues with administration officials. A dispute that cannot be resolved can result in tariffs being reimposed. Most companies indicated they would raise complaints through trade associations or anonymously, the survey found.
