China will support Jamaica to play a bigger role in world affairs, Foreign Minister Wang Yi has pledged, as the two countries aim to strengthen strategic alignment.

The message from China's top diplomat came as he wrapped up a six-nation tour with a visit to the Caribbean country.

Meeting Jamaican Prime Minister Andrew Holness in the capital Kingston on Saturday, Wang said China looked forward to expanding cooperation in trade, investment, new energy, agriculture, digital economy and the "blue economy", or the sustainable use of ocean resources.

"[We] support Jamaica in playing a more important role in regional and international affairs," a statement from the Chinese foreign ministry quoted Wang as saying.

According to the Chinese readout, Holness said Jamaica prioritised its relationship with China, was committed to building a strong strategic partnership and welcomed more Chinese investment.

In a post on social media platform X, formerly Twitter, Holness said Wang's visit was a "significant milestone" in diplomatic ties, "reflecting the enduring partnership and collaboration between our two great nations".

"We look forward to further strengthening the bonds that contribute to the prosperity and well-being of our people," he added.

Jamaica was the last stop of Wang's 10-day African and Latin American tour, which began with a visit to Egypt on January 13. This was followed by stops in Tunisia, Togo, Ivory Coast and Brazil.

While Africa has long been the first port of call for China's foreign minister in the new year, Brazil and Jamaica were added to the itinerary this year.

This was seen as aiming to boost China's charm offensive in the backyard of geopolitical rival the United States, as Beijing steps up engagement with the so-called Global South and urges greater say for developing countries in world affairs.

Jamaica was among the first Caribbean countries to sign a Belt and Road Initiative memorandum with China and the first in the western hemisphere to sign a related cooperation plan.

China was committed to the equality of countries regardless of size and the democratisation of international relations, Wang told Holness.

"[China] never interferes in the internal affairs of any country, never engages in geopolitical scrambles and never forces other countries to take sides," he said.

Wang also praised Jamaica's adherence to the one-China principle, while Holness said his country would continue to firmly adhere to its "one-China policy", according to the Chinese statement.

The one-China principle states that Taiwan is an inalienable part of China.

Beijing sees Taiwan as part of China to be reunited by force if necessary. Most countries, including the US, do not recognise Taiwan as an independent state, but Washington is opposed to any attempt to take the self-governed island by force and is committed to supplying it with weapons.

Seven of only 12 countries that still have formal diplomatic relations with Taipei are in the Caribbean and Latin America. They are Saint Vincent and the Grenadines, Saint Kitts and Nevis, Saint Lucia, Haiti, Belize, Guatemala and Paraguay.

The Pacific island of Nauru on Monday became the latest country to switch allegiance to Beijing. This came two days after Taiwan elected a new president, William Lai Ching-te, whose pro-independence stand has irked Beijing.

Taiwan's foreign ministry on Wednesday thanked the island's remaining allies after they pledged continued support.

Wang told Holness that China was willing to offer useful lessons to developing countries on modernisation approaches, and ready to develop closer people-to-people exchanges with Jamaica.

"The two sides could share governance experiences for mutual development," he said.

Holness said that China's success story offered lessons on achieving more efficient and equitable development, which Jamaica was keen to learn, the Chinese ministry readout said.

He also sought continued support from Beijing on improving the resilience of small island nations against climate change.
