Do China passport holders need a visa to visit GY?

Yes, Chinese ordinary passport holders need a visa for Guyana. China is NOT on Guyana's visa-exempt list (only diplomatic/service/official passports are exempt). Tourists must arrange a visa before travel: either an eVisa/visa authorization through Guyana's Department of Immigration and Citizenship, or a visa-on-arrival that requires a pre-approved invitation/approval letter from the Ministry of Home Affairs. A simple turn-up-and-pay visa on arrival without prior arrangement is not available. A Chinese citizen holding an ordinary passport requires a visa to enter Guyana for tourism. Guyana's Ministry of Foreign Affairs exempts only holders of Chinese diplomatic, service and public affairs passports; ordinary passport holders are not visa-exempt. Guyana does operate a "visa on arrival" framework, but for tourists it is conditional: the traveler must hold an approval/invitation letter from a sponsor or host that has been approved by the Ministry of Home Affairs (Department of Immigration and Citizenship) before departure, which is then converted to a visa at the port of entry. In practice this functions as an advance-arranged visa rather than a walk-up VoA. An eVisa/visa authorization can also be arranged in advance by contacting the Department of Immigration and Citizenship, with the fee paid on arrival. The standard visa fee is US$25 (US$35 expedited). Stays of up to 30 days are typically granted for tourism, with extensions possible, and passports must be valid for at least 6 months. Because a Chinese tourist cannot reliably obtain entry simply by arriving without prior approval, the conservative and accurate verdict is visa-required.
