Dealing with differences: Sinopec's acquisition of Addax Petroleum (A)
Sinopec Group, a state-owned Chinese oil and gas company, just acquired Addax Petroleum, a mid-sized Western European oil company with assets in Africa and the Middle East. Sinopec had embarked on an aggressive international expansion strategy as it sought to gain access to oil reserves outside of China. Based in Geneva, Switzerland, Addax Petroleum had grown rapidly via acquisitions and was considered a highly entrepreneurial international company.
