Has anyone else noticed that the US is letting China get away with all sorts of violations?

The Chinese are sending tainted and poisoned goods to the US. They recently refused to allow a US ship to dock in Hong Kongs harbor even though the waters were rough.The US government has done NOTHING to reprimand China for its actions. Is the fact that China is a strong trading partner with the US a reason for not taking any type of action?I'm not saying declaring war but I think the safety of the US citizens should be a higher priority than making overseas dollars off a country with horrible human rights violations. Why do we go after the smaller weak countries and let the bigger ones who pose a bigger threat scape on by??
