I would say there not on good terms for many reasons.

Example

Dead Sea Works claims the government's Sheshinski Committee violates its concession agreement.

Israel Chemicals Ltd. (TASE: ICL) has filed an arbitration claim over its concession agreement with the government for Dead Sea minerals. Israel Chemicals potash unit Dead Sea Works Ltd. has demanded full compensation for both current and future damage for what it terms “the government’s violation of the concession agreement.

According to Dead Sea Works, the need for arbitration arises from the examination the government is conducting through the Sheshinski 2 Committee to increase the royalties it pays for extracting Dead Sea minerals. The company claims this is a unilateral process, while Article 26 of the concession agreement defining operations between it and the government, dictates that any dispute should be referred to arbitration. Dead Sea Works suit claims the government is ignoring the agreement and is not only implementing the process unilaterally through the Sheshinski Committee, but also plans raising royalties Dead Sea Works will be required to pay
