The Saudi capital was bedecked with Chinese flags ahead of President Xi Jinping's visit on Wednesday that is likely to focus on energy ties but also follows months of tensions with the United States.
The red-and-gold Chinese emblem alternated with the green flag of Saudi Arabia along major roads in Riyadh, while Xi was pictured on the front pages of newspapers that highlighted the trip's potential economic benefits.
China, the world's second-biggest economy, is the top customer for oil from Saudi Arabia, the leading exporter of crude, and both sides appear keen to expand their relationship at a time of economic turmoil and geopolitical realignment.
The three-day trip — only Xi's third overseas journey since the coronavirus pandemic began, and his first to Saudi Arabia since 2016 — comes after US President Joe Biden's visit in July, when he pleaded in vain for higher oil production.

It will feature bilateral meetings with Saudi King Salman Bin Abdul Aziz and Crown Prince Mohammed Bin Salman as well as a summit with the six-member Gulf Cooperation Council and a wider China-Arab summit.
The programme represents the "largest-scale diplomatic activity between China and the Arab world since the founding of the PRC," or People's Republic of China, foreign ministry spokeswoman Mao Ning said on Wednesday.
The official Saudi Press Agency said the kingdom accounted for more than 20 per cent of Chinese investment in the Arab world between 2005 and 2020, "making it the biggest Arab country to receive Chinese investments during that period."
Oil markets are expected to be a top agenda item for talks between China and Saudi Arabia, especially given the turbulence the markets have experienced since Russia invaded Ukraine in February.
The G7 and European Union on Friday agreed to a $60-per-barrel price cap on Russian oil in an attempt to deny the Kremlin war resources, injecting further uncertainty into the markets.
On Sunday, the OPEC+ oil cartel led jointly by Saudi Arabia and Russia opted to keep in place production cuts of two million barrels per day approved in October.
Saudi and Chinese officials have provided scant information about the agenda, though Ali Shihabi, a Saudi analyst close to the government, said he expected "a number of agreements to be signed."
Beyond energy, analysts say leaders from the two countries will likely discuss potential deals that could see Chinese firms become more deeply involved in mega-projects that are central to Prince Mohammed's vision of diversifying the Saudi economy away from oil.
They include a futuristic $500 billion megacity known as NEOM, a so-called cognitive city that will depend heavily on facial recognition and surveillance technology.
