Which event angered americans am compelled the us government to send two strongly worded warning to germany in may an june 1915

The US was being provocked by Germany, as German naval forces and submarines had destroyed several US merchant vessels.

Before determing the participation of the US in WWI, President Wilson sent two written warnings to Germany, explicitly posing that the relations between the two countries were at a very delicate situation. Wilson wished to remain neutral in the conflict, but he knew that it would not be possible if German attacks continued. This is why he chose to use these warnings as a manner of giving a last opportunity to Germany before performing a direct intervention.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
