s closest neighbors and trading partners. those tariff threats rattled financial markets and the business community. we're joined now by mark zandi, chief economist for moody's analytics, great to have you. as always. i want to talk about the specific sectors and products that beijing is targeting with these retaliatory tariffs. coal, liquefied natural gas, crude oil, agricultural machinery, vehicles, certain metals. why those items well it's symbolic. >> you know, this. >> is a slight jab back in response to the trump administration's larger tariffs on china. i think they picked products that might be in industries that are more favorable to the trump administration's politics and policies. the fossil fuel industry would be a good example. the you mentioned liquefied natural gas, coal, crude oil, and of course, the farmers. the agricultural sector is very vulnerable to trade actions by china and while not stopping or exports of u.s. agricultural products to china or putting tariffs on u.s. agricultural products, they put it on ag machinery. again, more of a symbolic move just to say, hey, you know, we're going to respond if you push us too far here, but not go so far
