Does China subsidize export credit to reinforce its geopolitical aspirations?

(EXIM and Chatham House, 2019 and 2020) The U.S. 2019 approved reauthorization of EXIM included a goal of reserving not less than 20% of the agency’s total financing authority (i.e. $27 billion out of a total of $135 billion) "to support the extension of loans, guarantees, and insurance, at rates and on terms and other conditions, to the extent practicable, that are fully competitive with rates, terms, and other conditions established by the People’s Republic of China". The objective apparently being To directly neutralize export subsidies for competing goods and services financed by official export credit, tied aid, or blended financing provided by China or by other covered countries, i.e. to out-subsidize China's ECAs. In an October 2020 Chatham House conference speakers challenged the position that the Belt and Road Initiative (BRI) is a geopolitical strategy to ensnare countries in unsustainable debt and allow China undue influence. They noted that while the BRI is frequently portrayed as a geopolitical strategy that ensnares countries in unsustainable debt and allows China undue influence, the available evidence challenges this position, claiming that economic factors are the primary driver of current BRI projects. "China’s development financing system is too fragmented and poorly coordinated to pursue detailed strategic objectives; and developing-country governments and their associated political and economic interests determine the nature of BRI projects on their territory." Lee Jones of Queen Mary University of London added that "If 'debt-trap diplomacy' means that China is deliberately luring developing countries into unsustainable debt so that it can grab key loan-funded infrastructure like ports for geo-strategic purposes, then it is a total myth. There is simply no evidence that this has happened in any country." "Debunking the Myth of 'Debt-Trap Diplomacy': How Recipient Countries Shape China's Belt and Road Initiative" was released in August by Chatham House.
