Former Florida Governor Jeb Bush wants the US to intensify economic ties with Europe.

On Tuesday, Jeb gave his first major foreign policy speech as a presumptive presidential candidate in Berlin. The speech was delivered to the economic conference of German Chancellor Angela Merkel's Christian Democratic Union party.

The speech came a day after US President Barack Obama concluded a two-day trip to Germany for the G-7 meeting at a Bavarian resort. Obama and Merkel displayed their personal affection during the meeting. She pledged to continue the two nations' close ties and joint diplomatic projects.

The US's strongest European trading partner is Germany and the two countries work closely on a host of diplomatic issues. This includes the ongoing civil war in Ukraine and negotiations over Iran's nuclear program.

However, Jeb Bush's advisers said that he believes that Obama has abandoned too much of the diplomatic burden in Europe to Germany. Obama has won approval for sanctions against Russia for its backing of pro-Russian separatists in Ukraine from Germany.

Jeb said, "Seventy years after America and Western Europe began to build the post [World War II] architecture of security that alliance is as relevant as the day it was founded. Ukraine, a sovereign European nation, must be permitted to choose its own path".

Jeb has also planned to meet with business and government leaders in Germany privately as well as in Poland and Estonia over the course of the week. He wants to discuss the security threats to the region and to each individually.
