US Treasury Secretary Janet Yellen's recent visit to China has been hailed as a success in reviving communication channels between Washington and Beijing. The visit comes at a time when tensions between the two countries are high, with differences on issues such as climate change and debt relief. However, Yellen's trip has paved the way for potential cooperation in these areas.

China had suspended joint ventures and military communications with the US after Nancy Pelosi's visit to Taiwan last year, increasing the risk of armed conflict. Yellen's visit signifies a willingness to improve relations, despite the immense differences between the two governments.

One area of contention is climate change, where China does not want to contribute to a fund meant to benefit countries most affected by it. China argues that it is still a developing country and cannot pay like a rich nation. Additionally, China prefers to handle debt relief on its terms, avoiding involvement with international organizations like the World Bank or IMF.

Yellen's visit is a step in the right direction, as the two sides have begun to cultivate areas of cooperation again, including climate change and debt relief. While the differences remain, this visit shows that both sides see the need for engagement and diplomacy.

Overall, Yellen's visit to China has the potential to improve relations between the US and China, despite their diverse views. The question remains whether they can find common ground and work together on areas of mutual interest.
