Cohen then settled with his widowed sister, Leah Cooper, in Salford, England. There he was surrounded by siblings, nephews and nieces and became a beloved family patriarch. His standing as a loyal aide to Sun Yat-sen helped him maintain good relations with both Kuomintang and Chinese Communist leaders, and he soon was able to arrange consulting jobs with Vickers (planes), Rolls-Royce (engines) and Decca Radar. His last visit to China was during the start of the Cultural Revolution as an honoured guest of Zhou Enlai.
