sales in Vancouver—also thought to be affected by foreign purchasers—found that 18% of the transactions in Vancouver's most expensive neighborhoods were cash purchases, and 66% of the owners appeared to be Chinese nationals or recent arrivals from China. Calls for more data on foreign investors have been rejected by the provincial government. Chinese nationals accounted for 70% of 2014 Vancouver home sales for more than CA$3 million. On June 24, 2016 China CITIC Bank Corp filed suit in Canada against a Chinese citizen who borrowed CN¥50 million for his lumber business in China, but then withdrew roughly CA$7.5 million from the line of credit and left the country. He bought three houses in Vancouver and Surrey, British Columbia together valued at CA$7.3 million during a three-month period in June 2014. International banking "This issue will surely be raised at the G20 summit," predicted Tomasz Kozlowski, Ambassador of the European Union (EU) to India. "We need to strengthen international cooperation for exchange of tax information between tax authorities". Panama, Vanuatu and Lebanon may find themselves on a list of uncooperative tax havens that the Organisation for Economic Co-operation and Development (OECD) re-activated in July 2016 at the request of G20 nations, warned Le Monde, a French newspaper that participated in the investigation.

Countries meeting none of these criteria, such as Panama, Vanuatu and Lebanon, would go on the blacklist. Countries that meet only one criterion would go on the greylist. In April 2016, if this greylist had been in place it would have included nine countries: Antigua and Barbuda, Bahrain, Brunei, Dominica, Liberia, Nauru, Samoa, Tobago and the United Arab Emirates. Newsroom logistics The ICIJ helped organize the research and document review once Süddeutsche Zeitung (SZ) realized the scale of the work required to validate the authenticity of 2.6 terabytes of leaked data. They enlisted reporters and resources from The Guardian, the BBC, Le Monde, SonntagsZeitung, Falter, La Nación, German broadcasters NDR and WDR, and Austrian broadcaster ORF, and eventually many others. Ultimately, "reporters at 100 news media outlets working in
