Monday marks the final day of a six-day public hearing in Washington on tariff hikes on imports from China. Chinese companies attending the hearing have spoken out about the proposed additional 25 percent tariffs on 200 billion US dollars worth of Chinese goods. US companies, in turn, voiced their concerns. CGTN's Wu Lei has more, including reactions from some who were there.

Satsumas in airtight containers from Zhejiang Fomdas company. Since the late 1990's, they've been arguably the US's favorite Mandarin oranges. You'll find them in American supermarkets, schools and hospitals. But the US government plans to impose a 25 percent tariffs on satsumas. Zhejiang Fomdas' President just returned from the US public hearing about this.

XU XIAOFANG, PRESIDENT ZHEJIANG FOMDAS FOODS CO., LTD. "Our products account for over 95 percent of mandarin oranges in American markets. It is nearly impossible to find replacement in a short period of time."

After careful consideration, Xu decided to hire a senior American lawyer to represent the company at the hearing.

XU XIAOFANG, PRESIDENT ZHEJIANG FOMDAS FOODS CO., LTD. "We are not very familiar with American laws and regulations. An American attorney is better experienced in this regard."

After testimony from scores of Chinese companies, most called their products irreplaceable. They stressed that the tariffs will raise costs and increase burdens on American consumers. The companies say most products in question are not of strategic significance, and that the imposition of tariffs would not contribute to the goals stated in the US investigation. Associate Professor Yi Bo from Southeast University participated in the last three hearings.

YI BO, ASSOCIATE PROFESSOR SCHOOL OF LAW, SOUTHEAST UNIVERSITY "Compared with the previous two public hearings, which had only one Chinese company each time, this time six Chinese companies were in attendance. They all came prepared and played up their products a lot."

Yi says attending the public hearing does not guarantee a good result for these Chinese exporters. But, as the saying goes, you miss 100 percent of the shots you don't take.

WU LEI ZHEJIANG PROVINCE "As more Chinese companies go global, it is paramount for them to keep improving their core competitiveness. It is also incumbent upon them to study differences in various legal systems, so that they can be perceived in a positive light in front of judges and juries."

Many American businesses also voiced objections on the proposed additional tariffs. Yi says Chinese companies can learn from the American court appealing process.

YI BO, ASSOCIATE PROFESSOR SCHOOL OF LAW, SOUTHEAST UNIVERSITY "You can start by telling a warm, fuzzy, human story about the company and products, then you can elaborate the detailed reason on why your products need to be exempted from the list."

Xu says Chinese company representatives will have to wait four to six weeks for the final result. They are not sure when the trade tensions will subside, but they hope their high-quality products can be enjoyed by Americans and other world consumers. WL, CGTN, SHAOXING CITY IN ZHEJIANG PROVINCE.
