of resigning from various business positions, and in 2014 he concluded the process, as required by the Executive Ethics Code. This entailed his exit from Shanduka, from McDonald's South Africa, from platinum producer Lonmin, and from all other companies which might give rise to a conflict of interest, particularly in industries regulated by the government. His other interests – including a share trading company, his livestock farms, his property interests, and a sports car company – were placed in a blind trust. Parliament's 2014 Register of Members' Interests reflected over R76-million in company shares held by Ramaphosa (although that figure excluded shares held together with private individuals), as well as his ownership of 30 townhouses in Johannesburg and two apartments in Cape Town. Domestic role Alongside his duties as Deputy President, Ramaphosa was made Leader of Government Business in the National Assembly in terms of section 91(4) of the Constitution, a role which involved coordinating between Parliament and Zuma's cabinet. On 3 June, Zuma also appointed him the Chairman of the National Planning Commission, with Jeff Radebe as his deputy. In addition, Ramaphosa was responsible for developing a proposal to implement a national minimum wage, leading consultation on the matter between Zuma's administration and representatives of labour and business. The proposal was approved by cabinet in November 2017. In July 2014, Ramaphosa called for unity in the country after Julius Malema argued that the Afrikaans portion of the national anthem should be scrapped. Ramaphosa said, "We are about building a nation and we must extend a hand of friendship, a hand of continued reconciliation to those who feel that the national anthem does not represent them any longer, and it can happen on both sides". Late in Zuma's term, Ramaphosa also began to address publicly the widespread allegations of corruption in Zuma's administration. Foreign relations In 2018, Ramaphosa, in Zuma's stead, led South Africa's delegation to the World Economic Forum in Davos, to promote investment and business in South Africa. His other official trips abroad included a two-day working visit to Vietnam and Singapore, the objectives of which included consolidating trade relations, as well as the opportunity for South Africa to learn from the Singaporean economic model and the role it prescribed for state-owned enterprises. Ramaphosa also continued to serve as Zuma's Special Envoy during the mediation in the South Sudanese conflict, and participated in the Southern African Development Community
