A good method to improve diplomatic relations between two nations is through enhancing trade ties. Occasional diplomatic disputes are inevitable. Yet when two countries cooperate on mutually beneficial trade agreements, they are more likely to avoid letting political tensions stand in the way of a harmonious relationship.

By closely observing the Philippines' President Benigno Aquino's 5-day state visit to China this week, we can witness first-hand the two countries repairing tensions through closer business ties.

The China Daily reports, "China and the Philippines aim to double bilateral trade to $60 billion (U.S. dollars) in 2016, indicating that economic cooperation is a priority as the countries put aside the South China Sea dispute that has strained ties."

President Aquino secured a number of deals with China on Wednesday, while reiterating that there is much more to the Sino-Philippines' relations than maritime disputes.

Aquino participated in a one-hour meeting with Chinese President Hu Jintao along with their respective officials. They signed nine documents, which included a memorandum of understanding to strengthen cooperation between foreign ministries as well as a five-year trade and economic development program.

Talking more about trade and less about maritime disputes seems to be the right track for both countries. China has enjoyed tremendous economic growth over the past three decades while the Philippines continues to struggle with poor economic conditions. China must expand trade with Southeast Asian countries to maintain its strong economic growth. Meanwhile, Manila might spark a nationwide economic boom by working more closely with Beijing.

Besides, China has historically made efforts to maintain good relations with the Philippines. China was the first nation to offer an invitation to President Aquino on his inauguration day, June 30, 2010. Yet that invitation was delivered more than 1 year ago. This may explain why there was recent diplomatic tension.

Nevertheless, Aquino is making amends with his trip.
