In 2019，due to the weakening of the global economic growth momentum，consumer demand in the international market has gradually declined，and trade protectionism in European and American countries has continued to rise and heat up，further exacerbating the risks of complexity and uncertainty in the global market. However，under the background of many difficulties and challenges，China’s foreign trade still achieved growth against the trend. Not only did the scale of foreign trade hit a record high，but the structure of foreign trade was optimized，and the quality of foreign trade showed a steady improvement. The quality of trade has laid a good foundation. In 2019，the overall development of China’s service trade has been steadily rising，the trade deficit has shown a significant decline，the trade structure has been further optimized，and the service trade has gradually demonstrated the effects of high-quality development. Affected by the slowdown in global economic growth and intensified trade frictions，global foreign direct investment remained stagnant in 2019. The flow of Chinese foreign direct investment declined slightly，and the structure of foreign investment was further optimized. However，the cross-border mergers and acquisitions of Chinese enterprises have fallen sharply. The industries of cross-border mergers and acquisitions are mainly concentrated in high-tech and high-value-added emerging industries. The Asia-Pacific region has become the region with the most cross-border mergers and acquisitions activities. In addition，countries along the “Belt and Road” have become important markets for Chinese enterprises’ FDI.
