While I can't view images, I can provide some context based on historical trends. Generally, Vietnam has seen significant increases in exports since 2000, especially after joining the World Trade Organization (WTO) in 2007. Singapore is already a highly developed economy with established export markets, but it has continued to grow. Indonesia has also seen considerable growth, but not as steep as Vietnam's.
If you have specific data or figures regarding export growth from each of these countries, I could help analyze which country has experienced the greatest increase.
