Sweet potato is not only President Xi Jinping's favorite food, but he also sees it as a symbol of China's determination to make a contribution to global economic growth.
"The vines of the sweet potato may stretch in all directions, but they all grow out of its roots. Similarly, no matter what level of development it may reach, China, with its roots in the Asia-Pacific, will continue to contribute to the region's development and prosperity," Xi said in a speech in Lima, the capital of Peru, in November.
The president's remarks came as the global economy continued to struggle as a result of sluggish growth and as many Western countries embraced protectionist economic policies. Making China's mark in global economic governance and shouldering greater responsibility were the defining characteristics of Chinese diplomacy under Xi last year, according to observers.
The experts noted that contributing to world economic growth and offering solutions for global governance will be the guiding principles behind Chinese diplomacy this year. That will be especially true in May, when the country will host a grand summit to boost interconnectivity between potential partners in the Silk Road Economic Belt and the 21st Century Maritime Silk Road, known collectively as the Belt and Road Initiative.
In December, the Financial Times highlighted China's role in global governance, saying: "President-elect Donald Trump wants the US to shrug off its global responsibilities. China may grab the opening to move centre stage."
The article also pointed out that Xi has championed the Paris Agreement on climate change, defended the international community's nuclear deal with Iran and expanded trade liberalization within Asia.
International influence
Su Ge, president of the China Institute of International Studies, said the world economy is recovering slowly and with great difficulty, so better global governance is required.
"The deficit of global governance is growing. Western countries' abilities in terms of innovation and the provision of public services have been undermined," he said, adding that China's international influence became more pronounced last year.
Noting that China will hold two diplomatic events this year - the first International Cooperation Summit Forum on the Belt and Road Initiative and the ninth BRICS summit - Su said the country will remain a positive force in the maintenance of world peace, stability and development.
China's continuing efforts to press for sustainable growth and to improve global governance won the support of world leaders when they met for the G20 Summit in the lakeside city of Hangzhou, the capital of Zhejiang province, in September.
At the summit, Ban Kimoon, then-UN secretary-general, praised the efforts of China and the United States in the ratification of the landmark Paris Agreement.
The progress that had been made was a major success, according to Ban who praised the "outstanding leadership" demonstrated by Xi and US President Barack Obama, who handed over legal documents to him on Sept 3 as an indication of their resolve to jointly tackle the global challenge.
"In the past, it was often said that China was a major economic power, but unable to play a global leadership role commensurate with its new status," Paolo Garonna, professor of political economy at the LUISS University in Rome, told Xinhua News Agency during the summit. "Well, all of us in Hangzhou have seen the Chinese leadership in action, in terms of strength and quality, and its ability to deliver results."
