Chinese consumers are avoiding American products to show their support for their country in the tariff war with the US, according to a survey released by Brunswick Group.

Though more than three-quarters (77 percent) of Chinese say they often buy American goods, 56 percent of them have boycotted a US-made product because of the trade battle, which deals a blow to the bottom line of American manufacturers.

Nearly seven-in-ten (68 percent) of the 1,000 Chinese consumers polled by Brunswick say their opinion of American companies has gotten worse due to the trade dispute.

While the majority of Chinese consumers recognize the importance of bilateral trade between the two countries, few believe the dispute will be settled during the next three months.

The strategic communications firm also surveyed 1,000 Americans and found that trust in Chinese companies fell 12 points to 44 percent during the past eight months.

That finding, according to Brunswick, shows the need for Chinese enterprises needs to be "mitigating US regulatory and reputational risk."
